Question

An organic compound ' A ' contains nitrogen and chlorine. It dissolves readily in water to give a solution that turns litmus red. Titration of compound ' A ' with standard base indicates that the molecular weight of ' A ' is 131 &#177; 2 . When a sample of ' A ' is treated with aq. NaOH , a liquid separates which contains N but not Cl . Treatment of the obtained liquid with nitrous aci
