Question

In phenol carbon atom attached to -OH group undergoes -

  1. SP3 hybridisation          
  2. SP hybridisation
  3. SP2 hybridisation
  4. No hybridisation

Solution

(c) sp2 hybridisation
The carbon to which the hydroxyl group is bonded in phenol is sp2 hybridised. The increased s-character of the carbon orbital used to form the C—O bond makes it more electron-withdrawing. Thus, conjugation with the aromatic ring would make the sp2 hybridised oxygen atom more likely.

  Is there an error in this question or solution?
