When ethylamine react with sodium metal, the gas evolved is

Options

A $\mathrm{H}_{2}$
B $\mathrm{C}_{2} \mathrm{H}_{5}$
C $\mathrm{N}_{2}$
D $\mathrm{NH}_{3}$

Correct answer

A. $\mathrm{H}_{2}$

Step-by-step solution

When ethylamine is heated with sodium metal, then hydrogen gas is evolved.

2 \mathrm{C}_{2} \mathrm{H}_{5} \mathrm{NH}_{2}+2 \mathrm{Na} \longrightarrow 2 \mathrm{C}_{2} \mathrm{H}_{5} \overline{\mathrm{N}} \mathrm{HNa}^{+}+\mathrm{H}_{2} \uparrow
