Question

α-butylene when subjected to hydroboration oxidation reaction, yields ____________.

Options

• tert-butyl alcohol

• iso-butyl alcohol

• n-butyl alcohol

• sec-butyl alcohol

Answer 1

α-butylene when subjected to hydroboration oxidation reaction, yields n-butyl alcohol.

Explanation:

\[\ce{\underset{α-butylene}{6CH3 - CH2 - CH = CH2} + \underset{Diborane}{(BH3)2} ->[THE] 2(CH3 - CH2 - CH2 - CH2)3 - B}\]

\[\ce{(CH3 - CH2 - CH2 - CH2)3 - B ->[3HO - OH][OH^-] \underset{{n}-butyl alcohol}{3CH3 - CH2 - CH2 - CH2 - OH} + B(OH)3}\]
