Solution

The correct option is B (CH3)2NCH2CH2NHCH3

As only the secondary amines when reacts with Hinsberg reagent gives solid which is insoluble in alkali.

Option A and C are primary amines and the option D is tertiary amine.

Hence option B is correct option.

Q. Calcium burns in nitrogen to produce a white powder which dissolves in sufficient water to produce a gas A and an alkaline solution. The solution on exposure to air the produces a thin solid layer of B on the surface. Now that thin layer is peeled off and reacted with sulphuric acid and allowed to cool down and gain its water of hydration}. This compound is heated to 1000 K to give a black coloured compound X along with an acidic gas (Y).
