Carbylamine Reaction/ Isocyanide Test

In carbylamine reaction amine is treated with chloroform in presence of sodium hydroxide to produce isocyanide which has offensive / foul smell is called carbylamine reaction or isocyanide test.

This reaction is used to distinguish PRIMARY AMINE from SECONDARY / TERTIARY AMINE.

The isocyanide is poisonous gas, and Methyl isocyanide (CH₃NC) that is also called MIC gas was leaked in Bhopal, Madhypradesh state of India from a multinational factory, consequently a large number of people were died and injured and have been suffering till now.

Alpha, beta, gama and delta Carbon / Hydrogen

Alpha, beta, gama and delta Carbon / Hydrogen .
1. First carbon / hydrogen from functional group (in this case it is OH) is called ALPHA carbon and hydrogen present on alpha carbon is called ALPHA hydrogen.
2. Second carbon / hydrogen from functional group (in this case it is OH) is called BETA carbon and hydrogen present on alpha carbon is called BETA hydrogen.
3. Third carbon / hydrogen from functional group (in this case it is OH) is called GAMA carbon and hydrogen present on alpha carbon is called GAMA hydrogen.
4. Forth carbon / hydrogen from functional group (in this case it is OH) is called DELTA carbon and hydrogen present on alpha carbon is called DELTA hydrogen.

Sandmeyer Reaction 12th Standard

The reaction in which diazonium salt is treated with CuCl, CuBr or CuCN to produce Chlorobenzene, Bromobenzene and Benzene nitrile respectively is called Sandmeyer reaction.

Cannizzaro’s Reaction

The reaction in which the carbonyl compound (having no alpha hydrogen) is treated with base (NaOH or KOH) to produce alcohol and Carboxylate ion is called Cannizzaro’s reaction.

The cannizzro,s reaction is given by the aldehydes which has no alpha hydrogen.
The aldehyde oxidizes to carboxylate ion and reduced to alcohol.
Cannizzaro’s reaction is disproportionation reaction.
The reaction in which same molecule oxidizes and reduced simultaneously is called disproportionation reaction..

Question:- Which compounds gives Cannizzaro’s reaction out of the following compounds and why?
