Astarstudent said:hey u guys..what was ur answer for question 2. the one about showing ionic and dative bond..
is dative bond shown by arrows only (choice A) or shown by lone pair and arrow (choice C).
thanks
hassam said:DUDE IT WAS +1 AND -1....u said manganate oxidises OH ryt....so y +2 then it must be +1....dont tell me cold doesnt oxidise cos i never saw that thing anywhereBILALrox01 said:the change in Chiral was +2 and -1.. since the secondary OH will be oxidised to =0 leaving the cholestrol with one less chiral.

it was higher lower lower ..intel1993 said:sakibfaiyaz said:for 40 I gave D...

for 40th.....it was C..............calcium dont produce the compound the formula given wid ethanoic acid........\
and for bolztmann. it was lower high lower (it was option C think so)..............

I will wont argue about 40 as I dont remember the question clearly.
but boltzman would be : Higher Lower Lower http://jcsu.jesus.cam.ac.uk/~rpc25/note ... ltzman.gif
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
