Alkali metals are obtained by electrolysis of molten salt and not aqueous solution because H 2 is liberated at cathode instead of alkali metal.

Q. Assertion : Alkali metals are obtained by electrolysis of molten salt and not aqueous solution.
Reason : The discharge potential of $H^{+}$ ions is lower than alkali metal cation hence hydrogen is discharged at cathode instead of metal.
