A		p	Lieberman's nitroso reaction
B		q	Evolution of $N_2$ with $HN{O}_2$
C		r	Dye test
D		s	Green colour with $HN{O}_2$
		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)

$(a\to q,t)1^{\circ }$ aliphatic amine with $HN{O}_2$ gives alcohol and $N_2$ and also gives carbylamine test
$(b\to r,t)1^{\circ }$ aromatic amine gives dye test and also gives carbylamine test
$(c\to p)2^{\circ }$ aromatic gives $N$-nitroso compound with $HN{O}_2$, which gives Liebermann's nitroso reaction
$(d\to s)3^{\circ }$ aromatic gives $p$-nitroso compound which is green in colour
