The hydride ion `H^(-)` is stronger base than its hydroxide ion `OH^(-)`. Which of the following reaction will occut if sodium hydride is dissolved in water:-

Options

A. `H_((aq))^(-) + H_(2)O rarr H_(3)O^(+)`
B. `H_((aq))^(-)+H_(2)O rarr OH^(-)+H_(2)`
C. `H^(-)+H_(2)O rarr H_(2)+O_(2)`
D. `H^(-)+H_(2)O rarr` No reaction

Answer

B

Explanation

`H^(+)+ underset(H^(+)OH^(-))(H_(2)O)rarr underset(H_(2))(H^(+)H^(-)) +OH^(-)`
