Propane nitrile on alkaline hydrolysis gives “X” as final product and “Y” as the partial hydrolysis product. Y is

1. Partial Hydrolysis Product (Y):

During partial hydrolysis of a nitrile, the nitrile group (−CN) is converted into an **amide**.

For **propane nitrile**, partial hydrolysis yields **propionamide (CH₃CH₂CONH₂)** as the partial hydrolysis product.

Y = Propionamide

2. Complete Hydrolysis Product (X):

Upon complete hydrolysis, the nitrile group is converted into a **carboxylic acid**.

In the case of **propane nitrile**, complete hydrolysis gives **propionic acid (CH₃CH₂COOH)** as the final product.

X = Propionic acid

Correct Answer:

The partial hydrolysis product (Y) is Propionamide, which corresponds to Option a: Propionamide.
