Statement-I : `Li_(2)SO_(4)` do not form double salt like alum.
Statement-II : `Li` reacts with `NH_(3)` gas to form `LiNH_(2)`

Options

A. If both statement-I & Statement-II are True & the Statement-II is a correct explanatiom of the Statement-I.
B. If both statement-I & Statement-II are True but Statement-II is not a correct explanatiom of the Statement-I.
C. If statement-I is True but the Statement-II is False.
D. If statement-I is False but the Statement-II is True.

Answer

C

Explanation

Among sulphate salt of alkali metals only `Li_(2)SO_(4)` does not forms alum, as `Li^(+)` has very small size. `Li_(2)SO_(4)`
`Li` forms `Li_(2)NH` with `NH_(3)` gas.
