Question

Justify that electron donating groups are ring activating
groups
​

Answer 1

Answer:

Electron donating groups on a benzene ring are said to be activating, because they increase the rate of the second substitution so that it is higher than that of standard benzene. Electron donating groups are said to be ortho/para directing and they are activators.

Explanation:

An atom or group already attached to a benzene ring may direct an incoming electrophile to either the ortho‐para positions or the meta position. Atoms or groups that make the benzene molecule more reactive by increasing the ring's electron density are called activating groups.
