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
