Reduction of aldehyde , ketones and esters with No Alcohol is called Bouveault-blanc reduction .
The reaction produces a primary alcohol with methanol , a secondary alcohol with aldehydes ( except methanal ) and tertiary alcohol with ketones
( iv ) Hydrolysis of alkyl halides
R – X + KOH ( aq ) → ROH + KX
To avoid dehydrohalogenation of RX , mild alkalies like moist
Ease of hydrolysis of alkyl halides RI > R – Br > RCI > and t > s > p alkyl halides .
( v ) Hydrolysis of ethers
