Q. Which of these methods can be used to prepare alcohols?
I: Hydrolysis of cyanides
II: Hydration of olefins
III: Reduction of carbonyl compounds

AMUAMU 2012

Solution:

$I$. cyanides on complete hydrolysis give either carboxylic acids or their salts.
$II$. Olefins (alkenes) on hydration give alcohols (electrophilic addition mechanism).
$III$. Aldehydes, ketones, carboxylic acids can be reduced to alcohols.
