Chemistry 42....how did it go?..expected GT

[Nouman Shafique]

How did it go?....I found the paper lengthy, too many suggestions...Apps weere easy except Q7...
What GT u think ?

was so bad,...................wt about second que it was so irritating....

 

[ying27kia]

I found the paper was not difficult but tricky, esp the polymer quest, and entalphy.
Some repetition in section b

gt i think 58-63

can anyone start chat,,,.........................

I thought it was ridiculously easy.

I thought it was ridiculously easy.

it was not that difficult man, enthalpy required critical approach..as for NMR some good luck but u can never be sure abt suggestions, excluding all these parts, yeas the paper was relatively easier..

 

[histephenson007]

Quite easy

Can you stop repeating yourself
Looks quite retarded.

Hey guys for the question that is divided into two part, i wrote the wrong answer for the first however for the follow up question i wrote the correct, would i get 2 mark out of 2? or they will not consider the correct one in the second question

Did anyone get 0.0560 or something as the concentration of A in the electrochemistry/organic henna question?
also, what was used to reduce that compound? A strong reducing agent like LiALH4 right? because NaBH4 is too weak Im assuming

NO PAPER DISCUSSION

And for the polymer question, the monomers were a Dicarboxylic acid and a Dihydric Phenol right? (Phenol with 2 OH groups) and the modification would be to use instead of the phenol, a Di phenyl amine, so that Hydrogen bonds can form between amide chains ( Just like in secondary stucture of proteins)
And the conditions was NaOHaq and The Dihydric Phenol ( To produce the phenoxide ion) Heat under reflux with Conc H2So4, to remove the H2O

 

[mury456]

im expecting 40 ....
what grade should I expect ??

 

[h.alia]

was there any other hard or tricky questions ?!?!?!

not the carboxylic acid man ....that was the trrick .....it must ahave been acyl chloride....cos phenold doesnt reacts with carboxylic acid.....and come on chat leave discussion here....cum onj CHAT GUYX

I feel like it should have been easy but I messed it up. :/ Probably because I had about 3 hours of sleep and my head felt like it was gonna explode. I really hope the GT's low. Insh'Allah everyone does well.
