The strongest deactivating effect on benzene ring is

The nitro group is a very strong deactivating group Nitro benzene undergoes nitration at a rate only 10-4 times that of benzene. The nitro group is a meta-directing group. When nitrobenzene is nitrated with nitration mixture 93% of meta substituted product is formed. Ring deactivating groups are :

The most deactivating group for electrophilic substitution reaction in benzene ring is

The most deactivating group for electrophilic substitution reaction in benzene ring is

Which of the following froups groups deactivates the benzene ring towards electrophilic substitution ?

Why is halogen atom when attached to benzene ring is ortho and para directing but somewhat deactivating in nature?

STATEMENT – 1: In nitrobenzene, addition reactions are possible. because STATEMENT – 2 : Nitro group deactivated the benzene ring.
