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 nitratedwith nitration mixture 93% of meta substituted product is formed. Ring deactivating groups are :

1.	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 nitratedwith nitration mixture 93% of meta substituted product is formed. Ring deactivating groups are :
Answer» Ortho-PARA directing GENERALLY TAKES electron from phenyl ring gives electron to phenyl ring INCREASE electron density at meta & para. Solution :Ring deactivating group decrease the electron density in the aromatic ring by taking electrons.
