and concentrate on ur upcoming exams!!

im sooo worried.. i must get atleast 45... in this one.. omg what im gona do.

 

[larina]

What was the molecular formula of this leuco indigo or watever it was :/

it was C16H12O2N2 i dont remember it properly though

 

[m.r92]

What questions did you guys find the most difficult? Did you guys get the one involving lysone(?) ?

I got B in As but I was never told what I got in the individual units....

 

[h.alia]

same here

girls section ?!?!

Guyssss please tell meeee that the order of reaction was second with respect to NO and zero with hydrogen righttt???????????? And it was step 1 was the determining step which had 2 NO righttttt???????? Pleaseee some1 answer meeeee???

i got 2nd w.r.t NO and 1st w.r.t H2

It was 1st order with respect to hydrogen and 2nd order with respect Nitrogen monoxide

 

[user]

It was 1st order with respect to hydrogen and 2nd order with respect Nitrogen monoxide

and i put step 3 as rate determining step. You?

 

[larina]

and i put step 3 as rate determining step. You?

yeah it was 1 for H2 and 2 for NO, and the rate determining setp was 3

 

[user]

yeah it was 1 for H2 and 2 for NO, and the rate determining setp was 3

Alhumdulilah
and what reason did u give
and Aoa wr wb btw!

 

[rockchic]

What structures did you guys get for the organic chem part: with one compound turned into by reaction with HCl/heat?

Walaikumasalam wr wb!
i think i wrote because it consisted of H2 and 2NO in it

oh yeah that was a crazy question! i got it at the last minute!
for C8H15... it had CH3-C=O and NH2 and carboxyllic acid end and CH2 in between
for C4H5NO3 it had carboxyllic acid end, and CH3-C=O
and for C4H7NO it had -OH (secondary alcohol), -CN in it
and for the last one i dont remember...

 

[rockchic]

me toooooooo i got the same answers ! and for the last one i got something with a nitrile and something other O containing group- can't remember
and what about the last question of the conducting polymer- what did you put for the molecular geometry of the molecule??
