Options
- AOnly (I)
- BOnly (II)
- COnly (III)
- DOnly (IV)
Correct answer
B. Only (II)
Step-by-step solution
Reaction (I) represents the acid-catalyzed hydrolysis of an amide, which correctly yields a carboxylic acid (butanoic acid). Reaction (II) shows the reduction of an amide using LiAlH₄ . The reduction of a primary amide with LiAlH₄ yields a primary amine, not an alcohol. Thus, butanamide will reduce to butan-1-amine ( CH₃CH₂CH₂CH₂NH₂ ), not butan-1-ol. This reaction will NOT yield the product shown. Reaction (III) represents the base-catalyzed hydrolysis of an amide, which correctly yields a carboxylate ion (butanoa
