A compound with molecular formula `CH_(5)N` on treatment with `HNO_(2)` liberates a colourless and odourless gas. What is the name of the compound and the gas liberated ? Write the equation.

Explanation

`CH_(5)N` on treatment with `HNO_(2)` liberates a colourless and odourless gas. The name of the compound is methanamine and liberated gas is `N_(2) uarr`
`CH_(3)NH_(2) underset(HNO_(2))overset(NaNO_(2)+HCl)rarr [CH_(3)-N_(2)^(+) Cl^(-)] overset(H_(2)O)rarr underset("Alcohol")(CH_(3)OH)+N_(2) uarr +HCl`
