Title: as chemistry reaction mechanisms
Post by: superduper2009 on May 27, 2010, 03:14:05 pm

Can someone please explain the reaction mechanisms SN1 and SN2.
Also, how can we identify whether an organic reaction is nucleophilic or eletrophilic....and a substitution/elimination/addition ...
thanks in advance :D

lovely explanation that actually made me laugh  :D
do we need this for unit 2 ?
the mechanism question was asked in paper 1, is any further mechanisms required for unit 2?
