Had a good day of studying today, mainly focused on Русский (Russian). In college today we made banana bread and date scones which were really nice, I love being a culinary student but I really dislike the fact we have to pay for the things we bake ourselves. Apparently it was also ‘freshers’ week for universities so there was loads of stalls set up in the town centre where you would get massive discounts if you were a student.
To the boy who laughed at my Russian translation today иди нахуй! I’m trying my best here 🥲. Hey at least my bestie got my back though helping me correct it and tell me what I got wrong, forever grateful!

What comes to mind when you think of alcohol? Probably alcoholic drinks like beer or wine. But in organic chemistry alcohols are an important and versatile family of compounds. In this episode of Crash Course Organic Chemistry, we’ll use alcohols as a starting point to get other types of compounds like ethers, epoxides, and more!
Good news! You CAN rewire your brain. Through the same mechanism as forming habits, you can change your automatic thought patterns. When you catch yourself with unhealthy thoughts, STOP, and make a conscious effort to replace that thought pattern with a more beneficial/healthy thought pattern. Keep doing that whenever those thoughts occur. Slowly but surely your mind’s default voice will match what you’re teaching it.

Shapes of Molecules
his post is more information than trying to explain something - the truth is, you just need to learn shapes of molecules like you do with anything. I’ve got a physical chemistry mock tomorrow that I’m dreading since I’ve done zero revision. The fact that I run a study blog yet don’t revise myself is odd, but what else can I do? Oh, wait … revise. So here it is, my last minute revision for myself and you too - I present, shapes of molecules!
VSEPR stands for valence shell electron pair repulsion theory. If you’ve ever seen a moly-mod or a diagram of a molecule in 3D space, you may wonder how they decided it was that shape. Well, VSEPR answers all.
The theory essentially states that electron pairs are arranged to minimise repulsions between themselves - which makes sense, since electrons carry the same charge and therefore try to repel each other. Of course, there are different types of electron pairs, lone and bonding. The strongest repulsions happen between lone pair - lone pair followed by lone pair - bonding pair and finally, bonding pair - bonding pair have the least repulsion.
Since the repulsion governs the shape of the molecule, to work out a molecule’s shape you must look at dot and cross diagrams or electron configurations to see how a molecule is bonded. There are many methods to do this, but the bottom line is that you must work out how many bonding pairs of electrons and how many lone pairs are involved.
The easiest shape to learn is linear. This has two bonding pairs and no lone pairs at an angle of 180 degrees, since that is the furthest the two can get away from each other. Examples of linear molecules include carbon dioxide and beryllium chloride.
Next up is trigonal planar. This has three bonding pairs and no lone pairs, each at the angle of 120 degrees. Trigonal means three and planar means on one plane, this should help you in identifying the molecules since after a fourth pair of electrons, the shape becomes 3D. Examples of trigonal planar molecules include boron trifluoride and sulfur trioxide.
What if you were to have two bonding pairs and two lone pairs? Well, then you’d have a bent molecule. Water is a good example of a bent molecule. Since it has two lone pairs that repel the other two bonding pairs more than they repel each other, the bond angle is 104.5. I’d be careful though, as in many textbooks it shows a bent molecule to have one lone pair and a different bond angle.
Another variation of the bent molecule I’ve seen is the one with two bonding pairs and one lone pair. It is deemed as bent with a bond angle of 109 or sometimes less than 120 degrees.
Tetrahedral molecules have four bonding pairs and no lone pairs. The bond angle is 109.5 degrees. Examples of this include the ammonium ion, methane and the phosphate ion. A good thing to note here is how these molecules are drawn. To demonstrate the 3D shape, where the molecule moves onto a plane, it is represented with a dashed line and triangular line along with a regular straight line.
Trigonal pyramidal, sometimes just called pyramidal, is where there are three bonding pairs and a lone pair. Bond angles are roughly 107 degrees due to the repulsion from the lone pairs. An example of a trigonal pyramidal molecule is ammonia, which has a lone pair on the nitrogen.
Having five bonding pairs gives a trigonal bipyramidal structure. I guess the three bonding pairs on the trigonal plane accounts for that part of the name, where the rest comes from the position of the remaining two. These molecules have no lone pairs and have a bond angle of 90 degrees between the vertical elements and 120 degrees around the plane. Diagrams below are much clearer than my description! Examples of this include phosphorus pentachloride.
Six bonding pairs is an octahedral structure. I know this is confusing because octahedral should mean 8 but it’s one of those things we get over, like the fact sulfur isn’t spelt with a ph anymore. It’s actually to do with connecting the planes to form an octahedral shape.There are no lone pairs and each bond angle is a nice 90 degrees. Common examples include sulfur hexafluoride.
Square planar shapes occur when there are six bonding pairs and two lone pairs. All bond angles are 90 degrees! They take up this shape to minimise repulsions between electrons - examples include xenon tetrafluoride.
The final one to know is T-shape. This has three bonding pairs and two lone pairs. These molecules have bond angles of (less than) 90 degrees, usually a halogen trifluoride like chlorine trifluoride.
There are plenty more variations and things you could know about molecular geometry, but the truth is, there won’t be an extensive section on it. It’s a small part of a big topic!
I’m not going to do a summary today since I’d just be repeating the same information (I tried to keep it concise for you guys) so instead I’ll just leave you with,
Happy studying!
If you have trouble remembering all the beef two historical figures had for your exam, just start shipping them.
I am not joking.
They hated each other before their coalition? Enemies to lovers. One of them was assassinated? Right person wrong time. They have portraits/photos together? They must’ve fought the urge to hold hands.
You’ll be surprised by how easy their lore becomes to remember
When we all scroll through Tumblr pinterest Instagram etc we all see tidy desks, beautifully written lessons, revision sessions in nice cafes. But can we show the chaos that revision often represents? While romanticising our studies is enjoyable and can even be motivating, it's important to remember that most people don't work like that and still succeed. So here's my revision chaos 4 days before the start of my exams: binders everywhere, even on the floor, barely legible sheets of rough paper and my flat untidy due to lack of time. Yes, the greatest difficulty in studying is the lack of time, so don't focus on the aesthetics of your lessons, but above all on understanding them and making them interesting.
I guess Cesar doesn’t like geology…
I've been working on a research project for a few months and I've just sent my first results to my teachers. I'm very proud of myself but also very stressed about their opinions.
It's the first project I've done on my own, so it's far from perfect, but it's a start.
My biggest flex ? Using Saltburn and quotes Jacob Elordi in my french essay 🫡
Gradually falling back in love with studying 🫶
Doing organic chemistry always helps me enjoy what I study
I'm going to one of the most prestigious schools in my country. I don't want to go there because I like the studies or because I'll be well paid when I leave. Not just because there's a ball where you can carry a real sword (need I ask for a better reason?).
7 hours of work today, my eyes are starting to sting but at least I've been productive (which proves that working with stress is effective).
J-5 before exams
Exam season = chaos
(Actually I have exams every weeks so it’s always chaos)
Remember when I said in high school that I wanted to do a difficult degree to push my limits? I take back everything I said, let me sleep and have a social life.
Crying in front of mechanics or mathematics was not my idea of how I was going to spend my evenings as a university student…
More alcohol and fewer theorems would be better
I literally chose difficult studies (one of the most difficult courses in my country) to go beyond my limits, and I have the audacity to complain when it's actually beyond my limits.
It's only been two days since I returned to class and I'm already behind on work? Like how?
Am I procrastinating from reading my books for school while reading other books? Yes. will I regret it? probably. am I going to stop doing it? Never.
Hello it’s me Mohamad smeer this my anew account that’s account was blocked I’m 19 medical student palestinin from Gaza Now I study medicine and my family in north of gaza I need some money from living and for university I see that I’m starting lose my dream So I did this compgin plz if u can help me every dollar make difference for me
Thank u ❤️
https://www.gofundme.com/f/help-me-in-completing-my-medical-studies-please
Note !! the currency : Astralian dollar target is 7000USD for 2 years
Now we are 1400Aud its about 1000 usd can we reach 4000AUD by next week 😔 my university will start next month
Thanks you all ❤️❤️
