HOW WAS CHEMISTRY P42 MAY/JUNE 2017 (POLL)

[Sufia_at]

Delta H was 8 or -8?

how do you get that? I thought they said predict.

Is there any mark deduction for writing organic structures with pencil. They check them right?

No problem, they'll check it for sure.

they usually say, if it's too light, its not visible after scanning. So if you drew them dark enough, then no problem at all.

yeah same! i wrote -120 : p

I have also realized that people giving A level composite had an edge, as a lot of AS level was in there. I was one of these people.

exactly
I was thinking the same..
I had just revised all the AS because I was taking composite and I won't have done if I had been taking A2 only..
and therefore I could do all the halogen testing and mechanisms without problem.
I just checked up my bidentate isomers, I drew them correct!
So you are taking 33 tomorrow?
how is prep? any idea what's coming?

CIE be like...

Head examiner: OK ladies and gentlemen, how do we f*** up the candidates this time?
Examiner 1: Let's test the sh*t out of AS organic chemistry. Tests for halogenoalkanes anyone?
Head examiner: *chuckles* Let's see them b*tches remember that!
Examiner 1: Why don't we make a big ass table with AgNO3 / NaOH + HNO3 tests right in the beginning? That'll stop 'em from making the organic compounds since they don't remember the tests anyway!
Head examiner: You my buddy, ARE MY NEW BEST FRIEND!!
Examiner 3: Isomers! ISOMERS PLEASE!! CAN WE HAVE ISOMERS DADDY ?? I LOVE ISOMERS!
Head examiner: Ok ok calm down man we'll get it done geez...
Examiner 2: I know! Let's f*** up the equilibrium constants!
Examiner 3: On that note, we should f*** up the maths! Anyone up to make a weird a*s algebra question?
Examiner 2: Let's throw in some AS inorganic too!
Examiner 4: How about we leave out analytical chemistry and electrochemistry? That'll be a slap to all them stupid ass guess papers!

Head examiner: I f***ing love my job. Can't wait to write that examiner report on this one!

Why is this comment so lit!!! XD

Bro it was
Delta H = -100-(-92)=-8 ,delta H was -8
sorry i didn't put the sign.

 

[Qaussain]

What about the Mr and RCOOH question guys?

Mr was 81

 

[Metallic9896]

Mr was 81

It wasnt. I got 81 too and messed it all up. How did you write the formula with Mr 81? It was above 120 and it has to do with the equations written for NaOH and SO2. You and I probably made the same mistake of writing NaHSO3 as a product rather than Na2SO3.

i'm giving 34 9 days gap till my next exam!

so how was it for you guys??

i did 41. it was weird :/

Was that Angelic a functional group isomer for other U or T structures ??
And what were your bidentate isomers ??

I got the Mr 81 too

U

idk why i found the angelic acid Q. so easy. Maybe i did something wrong i was pretty sure of having correct answer during the paper. I'm a confused man.

CIE has confused our entire life

I did 41, and it was pretty bad too, I mean I can really tell, they skipped so many of the easy and scoring topics, we had so much of functional group testing and identifying structures... Hoping for the best
People in my centre mostly found it hard, some even ran out of time, and left the last question...

U

I left the angelic question because I thought I'll come back to it later, at the end, but ran out of time
the bidentate isomers were like this:
trans first then cis had it's optical isomer

what! are we supposed to put the charges?
