    CBSEENCH12010436

    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

    Solution

    (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)
