the type of alcohol in the alcoholic drinks we drink is a chemical called ethanol. To make alcohol, you need to put grain, fruits or vegetables through a process called fermentation (when yeast or bacteria react with the sugars in food-the by-productss are ethanol and carbon dioxide.

Here are some methods of prepar alcohol.

(1) From Haloalkanes

R-X +KOH(aq) -> R-OH + KX
Ex. -
CH3CH2Cl + KOH(aq) -> CH3CH2OH(aq) + KCl

(2) Reduction of Carboxylic acid and esters

R-COOH ------>R-CH2OH
(The Helpers of reaction are LiAlH4 And H2O)

Ex. -
CH3COOH --->CH3CH2OH
(The Helpers of reaction are LiAlH4 And H2O

(3) By hydrolysis of esters

R'-COOR +NaOH(aq) --->RCOONa + R'OH

Ex. -
CH3COOR +NaOH ---> RCOONa + CH3OH

(4) By hydration of alkene

CH2 = CH2 +H2O --H+-> CH3CH2OH

(5) By Aliphatic Primary Amines

R-NH2 + HNO2 ---> R-OH + N2 + H2O
(NaNO2/H2O)

Ex. -
CH3CH2NH2 + HNO2 ---> CH3CH2OH + N2 + H2O
