Which of the following is a moderately deactivating group in electrophilic aromatic substitution reactions?

Options

  1. AAmino (-NH 2 ) group
  2. BNitro (-NO 2 ) group
  3. CHydroxyl (-OH) group
  4. DMethyl (-CH 3 ) group

Correct answer

B. Nitro (-NO 2 ) group

Step-by-step solution

The nitro (-NO 2 ) group is moderately deactivating in electrophilic aromatic substitution reactions due to its strong -M effect and -I effect, which reduces electron density on the benzene ring.
