Description
I remember things better when pregnant women say them, so hopefully this will help me study for my final.I'm still screwed for remembering hydroboration and oxymercuration mechanisms though. D:

I know this is over two years since you asked this question, but I'm going to answer it anyways. Nu is the nucleophile (the molecule that is looking for something to attach to and share its electrons with, hence nucleophilic), and L means leaving group (the group that leaves in elimination and nucleophilic substitution reactions). As noted in the picture, it depends what reaction the molecule goes through, since it determines what happens (e.g. leaving group leaves first or at the same time etc.). Usually, it is better notation to have Nuc as the nucleophile and LG as the leaving group, but it's just notation so either way works. These are intermolecular reactions, but nucleophilic substitution and elimination reactions can also happen intramolecular (within the same molecule). An example of a possible scenario for an intramolecular nucleophilic substitution reaction could be a deprotonated alcohol group attacking the molecule next to it, kicking off a good LG such as a halogen ion (e.g. Chloride) and forming an epoxide, which is a strained 3-member ring with an neutrally-charged oxygen. This is pretty basic stuff (no pun intended) so if you're unclear on something or curious, there are probably tons of examples for these mechanisms.

Well it's been years since I've had an O-Chem class, so my best guess is... they're both magic.

I'm taking Organic Chemistry now, and it is a headache.

Why is it better if a pregnant woman say them? o.o

organic chemistry is my fav!!!
i hate the thermodynamix

oh Gosh I hate organic chemistry, we studied it in our second year at university... the teacher was stupid angry pig and we knew nothing but formules and none of the mechanisms so if you know them for now I envy you a bit

I just started Organic chemistry finally this year.

I'm glad to help. I wish you better luck than I had with O-chem.

Thanks. Got my test back today with a 97%.
Starting to see molecular structures everywhere I look.
:-|

Sure, I'll take credit for your 97.

Very nice work... I'm learning it those days... Very interesting ^^
Hope you had good results

THANK YOU. ...I think you just made me actually REMEMBER MECHANISMS. I have never been able to do so thus far. ;w;

LOL......i dont remember shit either.....Johnny Depp could be teaching me chemistry, and i'd just sit there like "WHHHHHUUUUUUTTTTTT????" (Chris Griffon voice XD)

@_@ omfg i have no idea what she is talking about, i don't think that would work for mei wouldn't be able to study, i'd be to mesmorised by her breasts...

Noooooo! I JUST ESCAPED ORGANIC CHEMISTRY AND NOW YOU BRING IT HERE?! AAAAAAHHHH! -dies-
Anywho. Cute <3

oddly enough, i failed highschool chem, while 2.5 years after i got an 80% in nio-chem (just one of those things...)

ohh, I meant bio-chem. Equations and the like ^_^

I just printed this off to help me pass my HUGE ASS o-chem exam tomorrow. lol thanks

Haha. Oh wow. Good luck.
Glad I could help.

Haha... pregnant ladies really are effective at pounding something in your brain.. I remembered that tidbit and it saved my ass on one question.. woohoo. But the other 2384723546234862847824 o-chem reactions (and mechanisms omgwtfbbq) kind of ruined it. Another way I remember SN2 - "If I was a reaction, I would be SN2 so I could attack your backside".
Umm... now i'm rambling because of a crazy lack of sleep. sorry
Good luck on your final if you haven't already written it

Me and you both I still have another one tommorrow ...and it's my off day tommorrow D:< Bah! stupid finals away with them I say! best of luck to the both of us dood

I'm done with all of mine.

XD This made my day, especially after plowing through my Advance Organic project...
As for the oxymercuration mechanism, don't fret too hard about it. Trust remember that you form the mercurinium (I believe that's the correct term) ion as a bridge across the site of the double bond. From then on I believe it just follows a standard Markonikov-type addition.
The hyrdroboration mechanism I'm not so good at, so I don't think I can give any advice on that... I believe it's an E2 type elimination if memory serves me right, with a four-membered transition state... but I could be wrong.
All in all though, I wish you the best of luck on the final!

Wow... my English on this SUCKED! Trust should be just, and Advance should be advanced...
This is what I get for working on chemistry until three in the morning X_X

Ughh. I haaate chemistry. If only a hot preggo girl like her would teach me, maybe I'd get a better grade... :< * has 20 pages of reading/make-up work to do*
π: 0 β©: 1
Aww. Stupid reading/make-up work. I know the feeling about that.
I like your sig, btw. It reminds me that I still need emo pants so I can dress up as an emo kid. I probably won't get REALLY tight ones though, even though that's the emo thing to do. That'd just feel wrong.
π: 0 β©: 1
Emo kids make me laugh. I know just about every one in my school, and are friends with most of them. XD

We all have different ways of motivation and such. The best of luck to ya then.

I wish I had cute preggy teachers when I still had chemistry, maybe it could interested me moreβ¦
π: 0 β©: 1
I had some cute preggy physics teachers. ...Coincidentally, I may switch to a more physics-based major.
π: 0 β©: 0
i got lucky, my major only has basic chemistry (whose final was coincidentally today) and i don't have to take organic...

At least you can have fun with your schoolwork. I'm forced to write stories during classtime...heh, that didn't come out quite right.
π: 0 β©: 1
Were you going for a double entendre or was it the "I'm forced to write stories" part that didn't come out right?
π: 0 β©: 1
The writing stories thing. I'm a writer. Writing stories should be fun!

FAR TOO MUCH SUGAR!

lol! That's one way to study...
Good luck on your finals. I'm about 10 hours away from being done with mine, if I survive that long of course.

Actually, this way is perfect for memorization. But that's thanks to a nice memory association trick a friend taught me.
Now I have all my formulas down.
