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??

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

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 :( :mad:
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]

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!
