Question:

Phenol undergoes electrophilic substitution more easily than benzene because

Updated On: Apr 15, 2024
  • -OH group exhibits +M effect and hence increases the electron density on the o- and p-positions.
  • oxocation is more stable than the carbocation
  • both (a) and (b)
  • -OH group exhibits acidic character

The Correct Option is C

Solution and Explanation

High stability of oxonium ion (oxocation) is because here every atom (except H) has a complete octet of electrons, while in carbocations, carbon bearing positive charge is having six electrons.

Alcohols, Phenols, and Ethers

Alcohol is formed when a saturated carbon atom bonds to a hydroxyl (-OH) group. It is an organic compound that contains a hydroxyl functional group attached to a carbon atom.

Phenol is formed when the -OH group replaces the hydrogen atom in benzene. It is an organic compound in which a hydroxyl group directly attaches to an aromatic hydrocarbon.

Ether is formed when oxygen atom bonds to two alkyl or aryl groups. It is an organic compound that has an oxygen atom that is connected to two aryl and alkyl groups.
