The nitro group is a very strong deactiv...

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 :

A

Ortho-para directing generally

B

takes electron from phenyl ring

C

gives electron to phenyl ring

D

increase electron density at meta & para.

Text Solution

Verified by Experts

The correct Answer is:
B
Ring deactivating group decrease the electron density in the aromatic ring by taking electrons.
