This question has multiple parts. work all the parts to get the most points. one method for preparing a nitrile is the dehydration of a primary amide. provide the mechanism for the reaction below: reaction a use curved arrows to show the mechanism of the step below. make the ends of your arrows specify the origin and destination of reorganizing electrons. arrow-pushing instructions b use curved arrows to show the mechanism of the step below. make the ends of your arrows specify the origin and destination of reorganizing electrons. arrow-pushing instructions c use curved arrows to show the mechanism of the step below. make the ends of your arrows specify the origin and destination of reorganizing electrons. arrow-pushing instructions d use curved arrows to show the mechanism of the step below. make the ends of your arrows specify the origin and destination of reorganizing electrons. arrow-pushing instructions

Following reaction shows the preparation of Nitrile from Amide. In this reaction Thionyl Chloride (SOCl₂)is reacted with Amide, which produced nitrile along with SO₂ and HCl gas. The importance of this reaction is the removal of byproducts (i.e SO₂ and HCl). As both SO₂ and HCl are gases so no extra workup is required to remove them. The mechanism of reaction is as follow,
