Question

What will be the final product in the following reaction sequence: \[ \text{CH}_3\text{CH}_2\text{CN} \xrightarrow{\text{H}^+ / \text{H}_2\text{O}} A \xrightarrow{\text{NH}_3} B \xrightarrow{\text{NaOBR}} C \]

• A. \( \text{CH}_3\text{CH}_2\text{CONH}_2 \)
• B. \( \text{CH}_3\text{CH}_2\text{COBR} \)
• C. \( \text{CH}_3\text{CH}_2\text{NH}_2 \)
• D. \( \text{CH}_3\text{CH}_2\text{NH}_2 \)

Hint:

Amides can be converted to amines by reduction with ammonia.

Answer 1

The Correct Option is C

Step 1: Hydrolysis of nitrile.
The hydrolysis of a nitrile (CH\(_3\)CH\(_2\)CN) leads to the formation of an amide (CH\(_3\)CH\(_2\)CONH\(_2\)).

Step 2: Reaction with ammonia.
When the amide reacts with ammonia, it undergoes reduction to form an amine.

Step 3: Conclusion.
The final product is the primary amine \( \text{CH}_3\text{CH}_2\text{NH}_2 \).
