Which of the following compounds will not show the test of nitrogen?

${\mathrm{NH}}_2\mathrm{OH}$ compounds will not show the test of nitrogen

Lassaigne's nitrogen test cannot be performed using hydroxylamine ${\mathrm{NH}}_2\mathrm{OH}$  or hydrazine (${\mathrm{H}}_2{\mathrm{NH}}_2$). These compounds lack carbon, hence the sodium extract produced under these circumstances does not include $\mathrm{NaCN}$.

Hence option C is correct
