chem p12...hmm that was a tough one !!!

[Astarstudent]

what was the answer of the cracking one? in which a product had 0.5 mole fraction?

i chose the one with C18 ..i think that was choice b. what did u put?

u also chose a random one? or u calculated it?

i actually calculated it..and it turns out to be B. my friends too got the same ans.. but of course we still cant say its 100% correct.

 

[Saad9bsq]

It should be B...C8H18...100% sure ...not random

ohk then i got it wrong.... 3 wrong till now :/

sakib
u remember in section B
there was the question
and three structure
and they gave when they are reacted with
k2cr2o7 it gives a non chiral center
which one was it??
btw its last question
sorry 4 disturbance

 

[Astarstudent]

is NO non polar or polar?

 

[Sannikutti]

It should be B...C8H18...100% sure ...not random

ohk then i got it wrong.... 3 wrong till now :/

yes cuz
it wouldbe 2*2+3+1

 

[intel1993]

actually when temp decreases left portion increases it becums higher lower lower

actually i knoe that but its just estimation but the sure thing that the peak height increases with decrease in temp whuch was section y hence
lower higher lower

@INTEL1993
WHAT WAS THE COMPOUND WHICH WHEN IT REACTS WITH K2CR2O7 DOES NOT HAVE CHIRAL CARBON\
LIKE THEY GAVE 3 STRUCTURES
IN SECTION B
THT QUESTION
LIK IT WAS SOME THING LIKE first one was attached to Cooh and other groups and one of group was CH2OH
???

 

[kakarocks]

Paper was Tricky actually , really made you think and check your Concepts . I being an A2 student got pissed as already having done p4,p5 i wasn't ready to think "once again" did all of it . However guessed randomly on about 5-6 question which were making me think! p.s What was the enthalpy change +720 no ?

 

[Sannikutti]

yes it was~

I dont exactly remember what the question had asked for..But I am sure I put D

 

[diwash]

Does any one remembers the answer of the Q no 31 ...the Q regarding adding water to a reaction...and the Q regarding the X, Y and Z gases(No and So2)....

 

[junaidaftab]

What were the options in the cracking of hydrocarbons question? What were options C and D, to the very least?

sakib what about the Q 31
the water one PLSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS

 

[diwash]

Someone plese answer me

 

[Sannikutti]

@divash
Q31.is B
Q about X,Y,Z is not sured
Q about gases was A

 

[Hateexams93]

what did u guys choose ?

 

[EzioAuditre]

for 31 i think it was D
AND Q39 it was D
and for pv one it was D

 

[Sannikutti]

Q31 is B
tell me the choices man
ill elaborate
