Can anyone explain to me why N(CH3)2 is a stronger activator then OCH3?
 
They both contribute via resonence. I think it is because there are two CH3-- there is more of an inductive affect? Not sure good question. Anyone else?
 
I think its cause the N is more willing to send its electrons into resonance than the O, which would prefer to hold onto them.
