[Chemistry 2] Questions

[lzxnl]

To "ionise" a hydrogen atom means to make it charged. The only way that can happen is to remove the electron, i.e. making the electron's final energy zero, thus freeing it.

Oh my God I'm an idiot it's ionising wtf am I doinggggggg
Yeah it goes from n=1 to infinity then and the 1/n(initial) approximates to 0 V:
The equation should still work, though (if you're reading this, MelonBar!) - nothing else is affected by my moronic mistake.

posting the night before the exam might be a stretch, but does anyone know if we need to know the antiperiplanar stuff for elimination reactions?
o.o its popped up on a couple exams now but i dont remember seeing anything about in the notes. :S:S not sure if it was mentioned in lectures since i don't go. OTLOTL

hey bro, apparently you do... :/

i dont rememberlearning it on the lectures as well

Yes you do. Is there anything in particular you'd like to know about it? All you really need to know is that there is a strict condition in E₂ elimination that the proton abstracted by the base and the leaving group are in an anti-periplanar arrangement with respect to each other, and that sometimes this will lead to a product which violates Zaitsev's rule.

D'8 there are exceptions to zaitstevs rule?!?! <///3333 MY LIFE IS A LIE
but i'l just remember that, thanks <3

Good luck for tomorrow (today?), everyone!
Crossing my fingers for the questions to be friendly and reasonably simple like the 2009/2012 exams...

I should have given nliu1995 a wig and asked him to sit the exam for me.

Dude, I haven't even done chemistry 2. I'm taking an exam in like three weeks, after my VCE and UMEP physics exam, to try and get an exemption from chemistry 1 and 2 next year due to the two weeks I spent at the ASI chemistry summer school (which actually covered everything in chemistry 1+2 plus more). Problem is, I've forgotten around half of it, so I have so much cramming to do in the week after UMEP physics.

nliu the resident boy genius

[lzxnl]

LOL just you wait and see my completely fail score

[scribble]

DW I CRAMMED ALL OF CHEM2 IN TWO DAYS.
though i did really badly in todays exam.
it was like "hint: dont invent weird ass chemistry" and i was "HAH I HAVE NO IDEA WHAT THIS REACTION IS, LETS MAKE SOME STUFF UP AND DRAW SOME ARROWS AND MAKE A BOND HERE AND OH LOOK ILL ADD SOME HYDROGEN SURELY THATS A GOOD IDEA :'D"
H3 here i come (Y)

I don't have lectures or the official notes to go by, just the notes I had from the summer school and my ability to decipher the notes I took.

Don't worry, that's like me in organic chemistry. I draw random arrows and hope the electrons do go there.

[scribble]

haha if you want, you can have all of my chem notes for the year. theyre all annotated in colourful pens but may or may not have chocolate stains on every second page. :'D
YEAH NAH SO MANY RANDOM ARROWS MAN. except that in my case theyre actually all wrong because i really have no clue ROFL. i drew smiley faces and hearts and wrote really irrelevant side comments all over my exam paper hoping that itd distract from the REALLY BAD CHEMISTRY

[LeviLamp]

Is this you actually worried about marks or are you going to pull another surprise 91?
