Question

Identify the major product C formed in the following reaction sequence: 

• A. Propylamine
• B. Butylamine
• C. butanamide
• D. α-bromobutane acid

Answer 1

The Correct Option is A

Step 1: Reaction with NaCN:

$CH_3 - CH_2 - CH_2 - I + NaCN \rightarrow CH_3 - CH_2 - CH_2 - CN$ (A)

Step 2: Partial hydrolysis of nitrile:

$CH_3 - CH_2 - CH_2 - CN + H_2O \rightarrow CH_3 - CH_2 - CH_2 - CONH_2$ (B)

Step 3: Hofmann degradation:

$CH_3 - CH_2 - CH_2 - CONH_2 + NaOH + Br_2 \rightarrow CH_3 - CH_2 - CH_2 - NH_2$ (C)

Thus, the major product is propylamine.

Answer 2

Step 1: Analyze the Reaction Sequence 

The given reaction sequence likely involves the reduction of an amide or ester to the corresponding amine.

Step 2: Predict the Major Product

From the reduction of butanamide, the product would be butylamine.

However, since the reaction likely involves both reduction and substitution, the most probable product is propylamine, which would result from a reaction involving butanamide.

Conclusion

The most probable product is propylamine.
