Hey piyush,

 

Isopropyl alcohol [ (CH3)2CH-OH ] ,  can be prepared by :

1. Hydration of Propene

    CH3CH=CH2 + H2O  + acid (catalyst) -------> (CH3)2CH-OH                                  .... (markovnikoffs addition)

2. Reduction of propanone by LiAlH4 or catalytic hydeogenation.

3. Oxymercuration demercuration of Propene.

1. reaction with sulfuric acid.

CH3CH=CH2+H2SO4--------->SULFATE ESTERS------->(on hydrolysis by steam) iso proryl alcohol.

2.hydration of propene(markovnikoffs addition)

CH3CH=CH2 + H2O  + acid (catalyst) -------> isopropyl alcohol.

3.Hydrogenation of acetone 

Crude acetone is hydrogenated in the liquid phase over raney nickel or a mixture of copper and chromium oxide to give isopropyl alcohol.
