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)
