Question

Statement 1: Hydroxylamine $\left(N{H}_{2}OH\right)$ contains $N$, and hence gives Prussian blue colour in Lassaigne's test
Statement 2: Hydroxylamine does not contain $C$, so with Na metal, $C{N}^{\ominus }$ ion is not formed

• A. Statement 1 is True, Statement 2 is True; Statement 2 is correct explanation for Statement 1
• B. Statement 1 is True, Statement 2 is True; Statement 2 is not correct explanation for Statement 1
• C. Statement 1 is True, Statement 2 is False
• D. Statement 1 is False, Statement 2 is True

Answer 1

Answer: (D)

(A) is wrong. It does not give positive test for $N$, since it does not contain C. So $C{N}^{\ominus }$ ion is not obtained which is anessential condition for the test for N. But (R) is correct
