A

`R-NC`

B

`CHCl_(3)`

C

Verified by Experts

The correct Answer is:
A, B
Carbylamine reaction Amine on reaction with a mixture of `CHuCl_(3)` and `KOH` produces alkyl isocynate `R-NH_(2)+CHCl_(3)+3KOH to RNC+3KCl+3H_(2)O`
Only RNC and `CHCl_(3)` are involved in carbylamine reaction. Hence(a) and (b) are correct.
