`X_(2)` is a greenish yellow gas with pungent offensive smell used in purification of water. It partially dissolves in `H_(2)O` to give a solution which turns blue litmus red. When `X_(2)` is passed through NaBr solution, `Br_(2)` is obtained.
What happens when `X_(2)` reacts with hot and conc. NaOH ? Give equation.
