Detailed Solution

The hydrolysis of phenyl isocyanide (C₆H₅NC) in the presence of acidic or basic conditions forms formic acid (HCOOH) and aniline (C₆H₅NH₂) as products.

Explanation:

Phenyl isocyanide undergoes hydrolysis where the isocyanide group (-NC) breaks down.
During this reaction:
- The -NC group is converted to a formic acid (-COOH) group.
- The phenyl group remains attached to the nitrogen, forming aniline.

Reaction:

C₆H₅NC + 2H₂O → C₆H₅NH₂ (aniline) + HCOOH (formic acid)

Correct Answer:

(b) Formic acid
