Method of preparation of alcohol from haloalkanes
Haloalkanes when treated with a dilute aqueous solution of an alkali or silver oxide give corresponding alcohols.
Alcohols through hydration
Alkenes can be converted to alcohols by direct or indirect addition of water in the presence of mineral acid by Markovnikov's or anti-Markovnikov's rule.
Preparation of alcohols by reduction of aldehydes and ketones
Carbonyl compounds such as aldehydes and ketones can be reduced to alcohols by using reducing agents such as lithium aluminium hydride etc .Aldehyde always form primary alcohols while ketone form secondary alcohol.
Preparation of alcohols by grignard reagent
Aldehyde with grignard reagent gives primary alcohol whereas ketone gives secondary and tertiary alcohol.
Dehydration by protonic acids
Alcohols, when treated with protonic acid, produce alkenes.
