Question

Identify major product 'B' in the following reaction.

\[\ce{But-1-ene ->[HBr][Peroxide] A ->[AgCN][\Delta] B}\]

Options

• isobutyl cyanide

• n-butyl isocyanide

• n-butyl cyanide

• sec-butyl isocyanide

Answer 1

n-butyl isocyanide

Explanation:

\[\ce{\underset{But-1-ene}{CH3 - CH2 - CH} = CH2 ->[HBr][Peroxide] \underset{1-Bromobutane}{CH3 - CH2 - CH2 - CH2 - Br} ->[AgCN][\Delta] \underset{{n-butyl isocyanide}}{CH3 - CH2 - CH2 - CH2 - NC}}\]
