The alcohol so formed
looks as if it has been formed by the addition of water to the
alkene in a way opposite to the Markovnikov’s rule In this reaction,
alcohol is obtained in excellent yield 2 From carbonyl compounds
(i) By reduction of aldehydes and ketones: Aldehydes and ketones
are reduced to the corresponding alcohols by addition of
hydrogen in the presence of catalysts (catalytic hydrogenation)
