Step-by-step solution

Step-by-Step Solution Step 1: Reduction of nitriles

Metal hydrides act as reagents for the reduction of alkenes to amine or aldehyde.

You can convert nitriles to amines using . An example is given below:

Reduction of nitrile to amine

Nitriles can be converted to aldehydes using DIBAL-H. An example is given below:

Reduction of nitrile to aldehyde

Determination of product

a. Alkyl bromide converts to nitrile initially upon treatment with cyanide. It is then reduced with . The reaction is shown below:
