how was chemistry paper 22

[A star]

Study of Group IV elements isn't in the AS Level course. We have never studied about Group IV bonds in AS.. I am pretty sure you're giving it accelerated hence why you know about it. So I am damn sure O and N are correct. since those are the only ones which we have studied about which have double and triple bonds.

yar forget it chill have apepsi xD

yar forget it chill have apepsi xD

I can't chill .. Have Computing paper coming up and I am not preparing at all .. -,-

Again is the question asking about pi bond or double bond? Double bond is not necessarily pi bond

well it is in AS level it is not in A2 people shold be aware the accelerate candidates

Double bond means 1 pi and 1 sigma bond. Triple bond means 1 sigma and 2 pi. In AS Level.

What? Nonono. I'm taking a two years course. We did learn about pi bond in AS. Is the question asking about pi bond or double bond, again?

question was name a substance that forms pie bond within its molecule

I see. O & N do form pi bonds. And C too. But don't confuse double bond with pi bond

 

[syed1995]

If all 3 answers are correct then what are we arguing about?

yar how can a substance forming single bond form pie bond? well forget it now

in the weak base question i did not include the equation, but stated only the defination how much mark will i get for this!

it was 91% awwwwwwwwwwwww yeeeeeeeeeeeeeahhh

i know i messed up the organic part but alhamdulilah rest was easy

C

LOL @ SB29597 exactly

btw what equation did you use to explain weak base?? nh3+ h20-> nh4+ +oh-? this one.

also what was the ester answer at the end, what is the identity of R? ethanoic acid??

Correct

 

[Waleed Amjad]

What is the organic product when METHANOIC acid is heated under reflux with acidified potassium dichromate(vi) ?

No reaction dude. how can acid get oxidized? Lol

 

[Waleed Amjad]

it is NH2^+ OH^-

No it is NH3 + H2O ---> NH4+ + OH-
