Which of the following compounds will not show the test of nitrogen?
Which of the following compounds will not show the test of nitrogen?
$\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{NH}_{2}$
$\mathrm{C}_{6} \mathrm{H}_{5} \mathrm{NH}_{2}$
$\mathrm{NH}_{2} \mathrm{OH}$
$\mathrm{NH}_{2} \mathrm{CONH}_{2}$
Solution
hydroxylamine $\left(\mathrm{NH}_{2} \mathrm{OH}ight.$ ) doesn't give a positive test for $\mathrm{N}$ since it does not contain $\mathrm{C}$. So $\mathrm{CN}^{\ominus}$ ion is not obtained which is an essential condition for the test for $\mathrm{N}$.
