Methods of Preparation of Alchohals

 

 

Methods of preparation

 

1.From alkyl halides:-

 

    

 

Not suitable for preparation of tertiary alcohols because tertiary halides, with strong base, prefer to undergo E2 elimination reaction.

 

 

2.By reduction of carbonyl compounds:

 

 

 

(H2 / Ni) is a very strong reducing agent, desides carboxyl, it also reduces olefinic bonds. A better reagent is which do not affect olefinic bonds.









4.Hydrolysis of Esters:

5.Hydration of alkenes:

 

 

 

6.Hydroboration – oxidation: (anti – markovnikov’s hydration of alkenes)
