  • Alkali metals cannot be extracted by reduction of their oxides and other compounds because

    A
    alkali metals are strong reducing agents
    B
    alkali metals have low ionisation enthalpy
    C
    alkali metals have high latice enthalpy
    D
    alkali metals are strongly basic in nature.

  • 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 metals cation hence hydrogen is dicharged at cathode instead of metal.

    A
    If both assertion and reason are true and reason is the correct explanation of assertion
    B
    If both assertion and reason are true but reason is not the correct explanation of assertion
    C
    If assertion is true but reason is false.
    D
    If both assertion and reason are false.
