Can someone explain how I am supposed to know which is least reactive compared to most reactive? I know that the benzene with the NO2 group on it is least reactive because it's an EWG (electron withdrawing group) so a deactivator but how do I compare the others? Thanks!!!
Homework Answers
The answer is:
c is most reactive because of the presence of CH3 group which has +I as well as hyperconjugation effect thus electron density is most for this compound.
between a and b , b is less reactive because although Br has a +R effect but it has -I effect too.thus reactivity is less.thus the order is:
d < b < a < c
