A. `C CI_(4)`
B. `CHCI_(3)`
C. `CH_(2)CI_(2)`
D. `CH_(3)CI`

Answer 1

Correct Answer - B
Aliphatic as well as aromatic primary amines form carbylamines (or isocyanides) when heated with chloroform and ethanolic postassium hydroxide.
`overset(RNH_(2))underset(AgNH_(2))(or)+CHCl_(3)+3KOH overset("ethanol")underset(Delta)rarr overset(RNC)underset("Carbylamine")underset(ArNC)(or)+3KCl+3H_(2)O`
