Solution:
this is an example of electrophilic substitution at para position of phenol, giving a coupling product.
Pianacol-pinacolone rearrangement, occur through carbocation intermediate.
Nucleophilic addition occur at $s p^{2}$ (planar) carbon, generating a chiral centre, hence product will be a racemic mixture.
