Chem exam tonight...should totally spam this thread with questions all day.
Protip don't mix francium with water.
On a more serious (not that mixing fucking francium with water isn't serious) note I am interested in chemistry, despite only having a basic high school knowledge of it.
[QUOTE=Angus725;39505629]I hear chem engineering is one of the harder engineering majors around. Our second years here have 4 hour labs every 2 weeks.[/QUOTE]
Yeah, it's definitely among the trickier ones, but at Scottish universities the first year is almost identical to what you do in 6th year of high school, which is why Scottish degrees are a year longer.
Hey cool a chemistry thread!
Next year I should have hopefully finished my chemistry degree.
In short: Radiochem and analytial rules, organic chemistry can suck my curly arrows.
[QUOTE=Jabberwocky;39504731]You should tell them the story of the woman (post-doctorate) who spilled a drop of some organomercury (dimethylmercury?) on her hands and some of it went through her latex gloves and her skin. She died within a year later because of it.
Here it is:

Of course, organomercury is more toxic than mercury chloride. They wouldn't let you near it if you died from touching it.[/QUOTE]
It's reasons like this why I'm terrified but fascinated by mercury!

Also had a chemistry test today, but it was only on equilibrium and acids and bases at standard level (All subjects at my school are done at SL the first year, then the HL the second year).
You should try out Richard Thornley's videos on IB chemistry if you haven't already as he literally covers every point on the syllabus and an option or two. You could almost skip every single class and only watch his videos and do fine :v:

where would you get francium..... O.o, its halflife is 22 minutes and its highly radioactive....
if you want something to not mix with water, the first two groups of the periodic table are a bad thing to mix with water

I have no idea how the American educational system works but having studied quite a lot of organic chemistry:
It's just a slightly different mindset. The theory behind it is a little bit less quantitative than other branches of chemistry, everything's relative (this reaction site is more electrophilic so maybe it will attack there etc). When it comes to organic synthesis it's often more about being skilled at techniques and some lateral thinking than just measuring out exact masses of reactants. Retrosynthesis just requires an absolutely bizarre mindset but is quite fun when you get it!

about 300 million reasons, usually tweaked out people playing with propane, lithium, volatile solvents, phosphorus... depending on route of synthesis.

[QUOTE=Boomslang;39504098]I'm currently studying for my chemistry degree! I would also like to say some people just shouldn't be allowed near toxic chemicals, for instance, despite being told the dangers of mercury (the mad as a hatter story) someone still found it rather funny when they poured Mercuric Chloride over their hands, that shits says [B]VERY TOXIC[/B] all over the bottle for christs sake![/QUOTE]
What were you using it for as it's a watched chemical given its handy relationship with aluminium in the same lab that just blew up?

I'm just getting into Organic Chem in my AP Chem class. My teacher said O.C. is the proving ground for medical students.
We are going to do 2 weeks of nomenclature of organic compounds and functional groups. My teacher showed us that a former student of his who pursued a chem degree thanked him for spending time on O.C. nomenclature because her college blew threw our entire course on O.C. in [B]one day[/B] and the rest of the time was spent learning new stuff.
Its hard because you need to learn and know stuff like what 2,3-dimenthyl pentane is and how to draw it and know what isomers are. By the end of the first day.
People don't learn it and when the prof. talks about reacting, say, 4-ethyl 4-iodo 6-menthyl octyne with some sort of chemical, nobody knows what the hell 4-ethyl 4-iodo 6-menthyl octyne is so they get stuck and can't keep and before you know it TEST DAY

Reminds me of my mechanics class right now. Our prof decided to do the entirety...ALL OF high school mechanics in 1 lecture... ds/dt=v, dv/dt=a are great equations >.>
On a side note, term test was easy as hell today. Total study time: 4 hours. Confidence: 85-90% correct.

I never thought about it like that but it's spot on. Organic and synthetic chemistry is like a lateral thinking puzzle where you have to use a toolbox of techniques that you've learnt.

I found organic I to be rather difficult. But organic II is a lot easier.
I blame my struggles in Organic I mostly on OsO4. Could never remember that OsO4 caused oxidation on both sp2 hybridized carbons instead of the most substituted on tests.
But once you get into benzene rings its much nicer. Reductive acylation is great.

Sometimes I feel like the only competent operator of the IR-ATR machine aside from the lab techs and supervisor. Everyone but me gets some sort of error when they hit the scan button.

I hate it when people use the IUPAC name of compounds with anything more than a few carbons and a couple of functional groups here and there. Just draw out the fucking thing and get it over with, dammit.

We were using it in a titration to determine the concentration of Fe(II) and Fe(III) in a mixed solution. I believe the Mercuric Chloride was used to react with excess tin in the solution. I had no idea about the reactions with aluminium, lucky there wasn't any nearby!
Al burns nicely...(for rocket fuel additive)
Starting a chemistry degree this october, any brits here at York or Bristol uni?
