Increasing Reactivty under Nucleophilic Addition
« on: September 30, 2011, 08:26:36 PM »
Hi Guys,

I just got my assignment back, and my professor gave us the answers of our assignment. I was wondering why the para-substituted NO2 was more reactive than the meta-substituted NO2.

Please find the picture below!

Thanks!

due to the angle differences in the bond perhaps??

Draw the resonance structures and consider the inductive effect

C=O carbon has δ+ charge, can you draw a resonance structure for the para nitro compound such that you end up with a +ve charge on the carbon adjacent to the C=O carbon?
