B		q	Evolution of $N _2$ with $HNO _2$
C		r	Dye test
D		s	Green colour with $HNO _2$
		t	Carbylamine test

• A. A- Q,t ,B- r,t ,C- p ,D- s
• B. A- r ,B-t ,C-p,s ,D- q,t
• C. A- t ,B-p,s ,C-q,t ,D- r
• D. A- p,s ,B-q,t ,C-r ,D- t

Answer 1

Answer: (A)

$(a \rightarrow q , t ) 1^{\circ}$ aliphatic amine with $HNO _2$ gives alcohol and $N _2$ and also gives carbylamine test
$( b \rightarrow r , t ) 1^{\circ}$ aromatic amine gives dye test and also gives carbylamine test
$( c \rightarrow p ) 2^{\circ}$ aromatic gives $N$-nitroso compound with $HNO _2$, which gives Liebermann's nitroso reaction
$( d \rightarrow s ) 3^{\circ}$ aromatic gives $p$-nitroso compound which is green in colour
