the new forum has been changed to [http://iit-redefined.theforum.name/index.php] . Join there immediately :) it has a lot of cool new features :)
in discussion Physical Chemistry / Chemical Kinetics » Chem kinetics doubt
then try and find out the answers to the questions asked :P :D if u want the answer :D
in discussion Physical Chemistry / Chemical Kinetics » Chem kinetics doubt
as i said it is not me who set the question…..
in discussion Moderator's Lounge / Site Design and functioning » Main Page Design
yes fixed that thanx :)
in discussion Physical Chemistry / Chemical Kinetics » Chem kinetics doubt
bcos u are refusing to answer certain necessary questions Huh? :D
in discussion Moderator's Lounge / Site Design and functioning » Main Page Design
Well, so do I. Ahhh! I know what mistake you are doing
Uncheck the option "Bind to IP" or like it.

why is everyone ignoring this question? :O

hey swadesi…… how do u know it is wrong? how can a chiral molecule posess a centre of symmetry? plz give examples….

im not saying sanyal is better. wiki def has more named reactions but watever is given in sanyal is more detailed

dont tell me sanyal is better, ill kill you :D

which one, the one by sanyal.

da vinci, i knw dat is what base material claims and so do many other books but dat is wrong. actually only molecules with plane of symmetry are achiral. a chiral molecule may or may not possess a cenre of symmetry. but if u ever get that question in your base tests dont ever rite wat i told u. i've tried telling it to kerur and smh but sometimesteachers think they are infallible.

dei, is there a provision to automatically log on everytime you come to wikidot, im irritated to type the password everytime :D
