The best method to prepare 3-methylbutan...

The best method to prepare 3-methylbutane-2-ol from 3-methylbut-1-ene is

A

addition of water in presence of dil. `H_(2)SO_(4)`

B

addition of HCl followed by reaction with dil. NaOH

C

hydroboration -oxidation reaction

D

Reimer-Tiemann reaction .

Text Solution

Verified by Experts

The correct Answer is:
A
`underset("3-Methylbut-1-ene"" ""3- Methylbutan-2-ol")(CH_3-underset(CH_3)underset(|)"CH"-CH=CH_2underset(H^+)overset(H_2O)rarrCH_3underset(CH_3)underset(|)"CH"-underset(OH)underset(|)CH-CH_3)`
The additon of `H_2O` in presence of acid take place according to Markovnikov's rule.
