Solution

The correct option is C B2H6 followed by H2O2

When propene reacts with mercuric acetate followed by NaBH4, it gives secondary or tertiary alcohols, in accordance with Markownikoff’s rule. But, with diborane followed by H2O2, it gives primary alcohols which is in accordance with Anti-Markownikoff’s rule. 6CH3CH=CH2+B2H6H2O2−−CH3CH2CH2OH
