A basic volatile compound gave a foul smelling gas when treated with `CHCl_(3)` and alc. KOH. A 0.295 g sample of the substance dissolved in aqueous HCl and treated with `NaNO_(3)` solution at `0^(@)C` liberated a colourless, odourless gas whose volume corresponds to 112 ml at STP. After the evolution of gas was complete, the aqueous solution gave an organic liquid which did not contain nitrogen and on boiling with `I_(2)` in the presence of alkali gave a yellow precipitate.
The compound must contain

`CH_(3)-NH_(2)`

`-underset(NH_(2))underset(|)CH-CH_(3)`

`-underset(OH)underset(|)CH-CH_(3)`

`-underset(CH_(3))underset(|)N-CH_(3)`

Verified by Experts

The correct Answer is:

`-underset(NH_(2))underset(|)CH-CH_(3)`

`CH_(3)-underset(NC)underset(|)CH-CH_(3)`

`CH_(3)-underset(NH-CH_(3))underset(|)CH-CH_(3)`

`CH_(3)-underset(OCH_(3))underset(|)CH-CH_(3)`
