WRITE ALL THE METHODS OF PREPARATION OF ALCOHOL
Answers
Isopropyl alcohol and tert-butyl alcohol also are manufactured by hydration of the corresponding alkenes. The industrial synthesis of methyl alcohol involves hydrogenation of carbon monoxide

Answer:
1. Hydrolysis of Halides
Alkyl halides when boiled with an aqueous solution of an alkali hydroxide give alcohol through nucleophilic substitution mechanism.
R-X + KOH → R-OH + KX
This general procedure produces primary and secondary alcohols. Glycerol can be synthesized from propylene by a series of reactions including the hydrolysis of a halide as one step in the process.
2. Hydroformylation of Alkenes
Lower molecular weight olefins react with carbon monoxide and hydrogen in the presence of a catalyst in a reaction called hydroformylation or the oxo reaction.
The resulting aldehyde is subsequently hydrogenated to form an alcohol.
