Chemistry General

Post pictures, papers, or discuss whatever you're working on.

Just had my first Chem midterm of college. It wasn't too bad, but chemistry is immense... maybe I'll stick to programming, where everything is a little more consistent.

With a little bit of chem knowledge, one can make dank compounds...

Chemistry general? Sounds great! I'm at uni and in organic chemistry right now. We're going to have our second exam on Friday, and I'm not very nervous about it because I scored near-perfect on the first one; the second exam will be on chirality (and related concepts), functional groups (so this >>10 is a good review for me), and SN1 & SN2 mechanisms. It shouldn't be so bad.

I recently did a lab on thin-layer chromatography (TLC), and that was really fun! Lane 1 is fluorene, lane 2 is fluorenol, lane 3 is fluorenone, lane 4 is the unknown (obviously fluorenol, as it moved the same distance as fluorenol), and lane 5 is the reference mixture. Dichloromethane was the solvent that was used.

If you have any chem questions, post them here and we'll try to help you with them. Also, if you ever need to look up chemical data, PubChem is your best friend! https://pubchem.ncbi.nlm.nih.gov/

Enjoyed some of the chemistry in HS (especially seeing how it relates to physics), thinking of doing https://ocw.mit.edu/courses/materials-science-and-engineering/3-091sc-introduction-to-solid-state-chemistry-fall-2010/ as a refresher and going further. Has anyone completed the course?

Second, is there any interesting (to you) combination of computer science/software engineering with chemistry? It could be research or just applications, thanks.


>Is there any interesting combination of computer science/software engineering with chemistry?
Yes, definitely; have you heard of computational chemistry? https://en.wikipedia.org/wiki/Computational_chemistry https://www.acs.org/content/acs/en/careers/college-to-career/chemistry-careers/computational-chemistry.html

From the ACS (American Chemical Society) page:
>Computational chemistry is not the same as computer science, although professionals in the two fields commonly collaborate.
>Computer scientists devote their time to developing and validating computer algorithms, software and hardware products, and data visualization capabilities.
>Computational chemists work with laboratory and theoretical scientists to apply these capabilities to modeling and simulation, data analysis, and visualization to support their research efforts.

I just had a friend who is majoring in chemistry decide to double major in chemistry and computer science so that he can become a computational chemist.


>Yes, definitely; have you heard of computational chemistry?
I have but unfortunately have never seen any of the work done in the field. From what I can tell there isn't anything that actually incorporates CS apart from running simulations which, in my view (im open to correction), wouldn't require much knowledge of CS/Software Engineering. All I see is chemists using R libs.

However, this looks fuarrrking awesome.


Funny, I got a Chemistry + Biology + Physics "blank" exam next Friday (I'm studying medicine). Pretty stressed about it, I have to know everything by heart and haven't done anything apart of electricity yet.
The cool thing is that chirality and functional groups are things I've already learned in middle school, 'cause colleges' programs haven't changed since the 90s while schools' one did.
The uncool thing is when teachers assume you already know something you never saw.
(the anime acide made me laugh)

don't worry, chemistry is a bit like programmation when you thing about it. Atoms are like tiny functions that do something particular when they come across other atoms (you "pass them" to other functions).
So molecules are like high-level functions, combinations of functions, as if you were programming in a functional language.

>tfw when only chem you know is from reading about bombs on the internet


anyone got any decent books / sources of books for chem?

I have Peter Sykes' Handbook to mechanism in chem but want some more physchem related stuff.


You do know about libgen.io and sci-hub.bz right? Is there something more specific you are looking for?


Recommendations more than the actual books


What areas interest you? How deep do you want to dive? What is the level of your current understanding?


Organic mainly, Im in sixth form (about undergraduate‚Äč 1st year level in America from what i can see)


Atkins' Physical Chemistry is kind of entry-level general physchem book. Also, you need to know mathematics, roughly the same maths that physicists need. Maybe after that some physical organic chemistry, if that's your thing.


any tips on doing chemistry at home and building a home lab? Been thinking about doing it but I'm still not sure.

>inb4 /drg/'s

This is not to manufacture drugs. Most edgiest thing I would make is thermite tbh and that doesn't even require a proper lab.


what exactly is the second pic describing/showing?


what turns into what inside your cells/body


I recently had a blast exploring what wood actually is. It is living tissue enriched with Lignin and now look at this son of a bitch. Holy soykaf, did you know that wood is a super complex thing to produce?

That fuarrrker is also largely responsible why paper making requires intensive chemicals and processing. It is the glue that holds fibers together.

In pic: a former pulp factory which produced hundreds of tonnes of pulp per day.


I hate doing TLC. It always fuarrrks up. Also organic redox stoichiometry is such a hassle.

I'm also conflicted about choosing a chemistry oriented education VS computer science. I like both, although I absolutely don't wanna do medicine or anything biology related in chemistry, which seems to be a focus. And computer science I can pretty much study on my own and get a programming job.

I need moar input Lains.


I know someone doing a combined math/chem degree. She claims that the math aspect is harder, but helps *a lot* with understanding chem.

With a CS+chem degree you can probably get all the fancy jobs doing protein folding modelling or whatever.
