Question

Propane nitrile on reaction with ethyl magnesium iodide in presence of dry ether gives complex. This imine complex on acid hydrolysis forms ______.

Options

• propanone

• 2-pentanone

• butanone

• 3-pentanone

Answer 1

Propane nitrile on reaction with ethyl magnesium iodide in presence of dry ether gives complex. This imine complex on acid hydrolysis forms 3-pentanone.

Explanation:
