QJEEM21Ch5411: JEE Main 2021 Chemistry - Class 12 JEEM21Ch5411 Solution: Compound A is converted to B on reaction with CHCl 3 and KOH.…
Compound A is converted to B on reaction with CHCl3 and KOH. The compound B is toxic and can be decomposed by C. A, B and C respectively are :
Multiple Choice Options
- A primary amine, nitrile compound, conc. HCl
- B secondary amine, isonitrile compound, conc. NaOH
- C primary amine, isonitrile compound, conc. HCl
- D secondary amine, nitrile compound, conc. NaOH
Step-by-Step Verified Solution
Primary amine reacts in presence of chloroform gives isonitrile which is toxic in nature which further reacts in presence of HCl/H3O+ to give primary amine and acid.

Hence, A-primary amine, B-isonitrile compound and C-conc. HCl.
