Homework Answers
meta director groups are -NO2 (nitro group), -CO2R (ester group), - SO3H (sulfonic acid group), -CO2H (carboxylic acid group) -CHO (aldehyde group) , ketone group etc.
All the above groups are meta orienting group because -R effect.
-NH2 (amine), -OH (alcohol), -CH3, - NHCOCH3 etc are ortho para orienting groups because these are +R group.

Nitro group (-NO.) as a strong deactivator, is a me tivator is a meta-director in electrophilie substitution reactions. Why? A) Because it decreases electron density mostly on ortho and para positions, thus making meta positions better reactive sites, B) Because it deactivates ortho and para positions and activates the meta positions. c) Because all deactivators are meta-directors. D) Because its resonance effect competes against its inductive effect and the resonance effect increases the electron density on meta positions. E) All...
