Question

Lassaigne?? test for the detection of nitrogen fails in

$H_2N - CO - NHNH_2 \cdot HCl$

$NH_2 - NH_2 \cdot HCl$

$C_6H_5 NH - NH_2 \cdot HCl$

$C_6H_5CONH_2$

Answer

$NH_2 - NH_2 \cdot HCl$

Explanation

Solution

Lassaigne?? test is given by those nitrogenous compounds in which carbon is also present along with nitrogen. In ${NH2 ??NH2.HCl,}$ carbon is absent, so it does not give Lassaigne?? test
