stop dicussing...

 

[Nibz]

oh tht was a tricky one, bt i still got that, it was C! 30cm^3
lol we r nt supposed to discuss the ppr before 24 hrs

But you just did.

 

[sl0wDowN2]

i would tell you wat i got but now i cant

 

[SalmanPakRocks]

Feel free to Discuss the paper now as 24 hours have passed !!

 

[theawesomist]

OhMyGod!! I made such silly mistakes!! ufff

Kay guys howd your paper go? Mine went averagely bad... What did u guys get for the one with student X and Y with 17 carbon atoms in one plane and the cis trans isomerism thing? And what about the previous centuary Haber process pressure changes? I wrote Iron catalyst for that one.... :s And XYZ halogens reducing power with the X^- and Y^- and Z^- ? I think I did ZXY... And the first question in section B with the Bronsted Lewis acid-base theory I did D ....What abt u guys??

 

[Hateexams93]

urs seems to be easier :/ paper 12 was just bad

 

[sl0wDowN2]

question 31 was B i think....because H2SO4 is not a acid with C2H5OH...its a dehydrating agent, so it must have been correct, for the pressure one...its to reduces expenses koz a very high pressure is extremely expensive....the one with X^-, Y^- and Z^-...Y^- was definately the weakest.. im Z^- only showed one change....therefore it had to be XZY

Are u sure bout ques 31 cause i also did D :S....nd wat bout that student X and Y ques??..and wat were da enthalpy chnge answers??

 

[ullahabd]

Pper was good alhamdullelah..........i got 31 as B

 

[Islu_jf]

I got the X and Y Students as neither of them .. same question came in Oct/nov 2011 //
I got 0 for the chiral centre and its 1
I got 30 cm^3 as Volume
the enthalpy i got -202 somthng,, i hope its right..

Yeh lool even i wrote 0 lool...and yeh i got -202 ....and yeh your x and y r ryt.....man i got the volume as 15 =S [/quote]

 

[ivorydale]

my paper wasnt all that good because for few of the questions i first marked the correct ans but then changed it to a wrong one

hyyy i gotttt minus four hundred sumthng :S:S and da chiral carbons werent zero..nd ya i also got da voume 30 cubic cm

 

[Islu_jf]

il manage to get the paper tomorrow n wel discuss it

 

[sweetyrox]

oohhhkk den see u tmrw again in dis thread yaa?

whoa! about the bond enthalpy!? How can it be negative! bond enthalpies are always quoted in positive, since it the amount of energy required to break the bond! And if I remember, the molecule was X2H6 , so it was a single bond between X-X . I got +404!

by calculation i got -404...

yeah inshallah.. just wish me luck in stealing them ..

but do u guys remmber anything? i really wanna count my mistakes.. i do alot of silly ones.
