An organic compound `(C_3H_9N)` `(A)` when treated with nitrous acid , gave an alcohol and `N_2` gas was evolved. (A) on warming with `CHCl_3` and caustiv potash gave `(C)` which on reduction gave isopropylmethylamine. Predict the structure of (A).

A

B

`CH_3CH_2-NH-CH_2`

C

`CH_3-undersetunderset(CH_3)|N-CH_2`

D

`CH_3CH_2CH_2-NH_2`

Text Solution

Verified by Experts

The correct Answer is:
A
When nitrous acid react with primary amine it gives an alcohol and `N_2` gas. So, A should be primary amine.
`C_3H_7NH_2 + HNO_2 overset(NaNO_2 + HCl)to C_3H_7OH + N_2 + H_2O `
