Question

How would you obtain the following?

(i) Benzoquinone from phenol

(ii) 2-methyl propan-2-ol from methyl-magnesium bromide

 (iii) Propane-2-ol from propene

Answer

(i) Phenol is oxidised to benzoquinone as

 

It is an oxidation reaction. The ready oxidation of phenol is explained by the fact that the presence of OH group on the benzene ring increases electron density to the ring due to resonance which makes it for the oxidation reaction.

(ii)

 

 

 

(iii) If the propene is allowed to react with water in the presence ofan acid as catalyst, then propan-2-ol is obtained.
