The day has come and you’re finally forced to take that one class you avoided for many years - organic chemistry. Like most people, studying for chemistry is not particularly favored and can be tricky to know exactly what to study. It takes a lot more effort and time management for students; in which, the outcome is not always what they expected. Though, as a chemistry major and someone who got a reality check when going through the first semester of organic I want to give some personal tips on how/what to study!


1. Read the chapters assigned before lecture!
This is something that many students forget about or don’t feel like doing. (Haha, me) However, trust me it is the best thing you can do in organic because there will be days that you have NO IDEA what the teacher is talking about. Though, one day I decided to read the chapter with corresponding mini-notes in my notebook before the lecture and man did it help. This can be done the day before or even an hour before lecture (I prefer before lecture so it’s fresh in my mind) and it helped me know what questions to ask!

2. Ask questions or answer questions!
Yes, if you’re like me and get anxious to raise your hand this will be difficult to accomplish but once you break out of that comfort zone… it’ll be beneficial. Also, don’t be embarrassed if your answer is wrong! It helps to know why you didn’t get it right when the teacher goes on to explain the correct answer. This will help you change your thought process about the problems when you especially get into synthesis reactions and elimination reactions.

3. Revise notes after lecture!
After the lecture, if I didn’t have another class right after, I would take a colored pen and write side notes to revise them. Basically, this helped me make personal connections with the material. Note: can vary between each student so do whatever you’re comfortable with! 

4. DO PRACTICE PROBLEMS!!!!
No seriously.. Do every problem you can so the material and concepts can be drilled in your brain! When you get to alcohol synthesis, this is definitely important because those reactions can’t just be memorized. You’ll have to know the products formed and what solvent you need to use in order for the reaction to actually work.

5. Make flashcards!
I made them for the important things to know in my notes. By doing this, I could focus on the material that was the trickiest for me. Also, concept maps work for organic because it gives you a good layout of the chapter! 

6. Put some color in those notes!
This can help you navigate through your notes better and know how the reactions work. So, if you’re given an example of an SN2 reaction put the reactants in black pen, the solvent in red pen and the main products in blue pen. This can help know which compound is the electrophile and which one is the nucleophile. (I wrote little side notes on why they are each one for when I looked back at it) 

7. Buy Organic Chemistry as a Second Language by David Klein.
Or any other secondary textbook that gives extra help. The one I mentioned is particularly excellent because it’s in the format of a workbook and is divided by both semesters (I and II). The author has readings of each chapter and then works through problems with you to better your understanding of the concepts. (There’s more problems at the end of each section if needed with an answer key.) 

8. Go to the professor’s office hours!
Very straight forward tip… They like when you show interest in excelling in their class!


So there’s my take on organic and I hope everyone who is taking the class finds these tips helpful. Don’t be afraid to add more to this post with anything that helped you personally. Good luck!

GF Valentine Headcanon

One year, Dipper makes Pacifica a Valentine’s Day card. It’s cheesy and covered in lace and glitter and it has a chemistry beaker on the front, with text saying ‘We mix well together! Will you be my Valentine?’

He even gathers enough courage to stick it in an envelope and write her address on the back. He doesn’t, however, have enough courage to put on a stamp and mail it.

So when he discovers it missing one day, he’s rightly panicked. The panic turns into hysteria when Mabel innocently claims that she thought it was meant to be mailed and sent it off with the rest of her Valentines

(she knew very well Pacifica was never intended to see it but she’s Mabel the Matchmaker)

Dipper agonizes for days and knows Pacifica will never let him live this down. Until he gets a text on Valentine’s Day.

I don’t normally date dorks. But I guess I’ll make an exception. You may have the honour of being my Valentine.’

Dipper is in a bit of daze after that and spends the evening having a video chat/dinner date with Pacifica, and she is quickly dropped from her high and mighty position when Dipper spots through the web cam that she framed his Valentine and hung it up. This breaks the ice and the awkward atmosphere from the first couple of minutes of their chat disappears

(Mabel tries to eavesdrop from outside the bedroom door but Dipper eventually catches her and throws a pillow at her. She then proceeds to shout about Dipper’s girlfriend and show pictures of her to everyone at their school and spams Pacifica with texts saying Pacifica Pines)

JK: This is how Jenna and I really became friends, too. ‘Cause we were told just to kinda feel it out.

BJ: Greg or Ken would often say, you know, “Just flirt. Just talk. Just be friendly.”

JK: Which I thought was going to be really scary, but uh…

BJ: It came very easily to you two.

JK: It did. I mean, Jenna was really…

RW: One word. Chemistry.

JK: Chemistry. And not beakers and bubbles. We’re talkin’ connections.

Preparing a nitrating solution from 100% nitric acid and phosphorous pentoxide.

Just a few short notes: the 98-100% nitric acid is a quite strong oxidizer. If I would spill it on my gloves it would ignite it in no time. Same would happen if I would spill it on my labcoat.

From the reaction of pure nitric acid and phosphorous pentoxide, nitrogen pentoxide is generated what is also known as the anhydrous form of nitric acid: N2O5 + H2O = 2 HNO3.

The dinitrogen pentoxide is a highly reactive white powder, melting at 41 °C. When it contacts with water, even with the humidity of the air, it produces nitric acid what is quite corrosive (those fumes what are coming out from the beaker). However, it is a great reagent if you would like to prepare a nitrate ester of any compound what you can found on the shelf.

Y-Yes Professor!: 707/MC

so I know I posted this on AO3 but I didn’t post it here, please enjoy~

Summary: MC knows that neither Saeyoung or Saeran have any fond school time memories, she aims to change this; and what better way than dressing up as a university professor for a day? 

FLUFF/ college AU kinda

Saeran had always wanted to go to school. He didn’t tell anyone this but you could see it when he and Saeyoung picked you up from university. Although he rarely spoke out of turn you could tell from the faraway glimmer in his eyes something about campus life fascinated him endlessly. You had offered them a tour on one of these visits, you were in your last year there and you knew the campus well. From building to building you went, even Saeyoung seemed like he was having fun; his university life had been shortened due to his genius, so he lacked fond memories of the time. They both thoroughly enjoyed the chemistry lab, where beakers bubbled and where there were various gadgets to touch and explore. The memory was a happy one yet it saddened you slightly; these two had never once lived a normal life, surrounded by peers and laughter, it was foreign to both of them. It was then that an idea struck you, late one night at Saeyoung’s bunker- you’d bring them to university and teach a class!
If they couldn’t enroll formally, for numerous reasons, then you could at least try to emulate a university experience for them. It would be a gift of sorts, the least you could do to try to alleviate the stress between the two of them and from their past lives. It required a bit of planning of course, you had to ask for permission to use a classroom, purchase some supplies for them but it would be entirely worth it. Once the dates had been set it was becoming increasingly hard not to tell them of your plan.

Large format photography project in one of my classes. I chose to take pictures of Hood 32! :) If you’re wondering, I did mess it up a bit to make the pictures more interesting…I’m usually WAY cleaner than this. 

These types of cameras are the old-fashioned ones where you put your head under a blanket and click the little button thing… know what I’m talking about? 

These are just scans of the negatives, and that’s why they’re so crooked and not awesome looking with a bunch of dust on them. The ones I have printed look great. It was pretty fun to do and I’m glad I got to mix chemistry and art!
