    The most stable compound is

    A) \[LiF\]                                  

    B) \[LiCl\]

    C) \[LiBr\]                

    D) \[Lil\]

    Correct Answer: A

    Solution :

    The electronegativity of halogen is as:                 \[F>Cl>Br>I\] Among alkali metals the electropositive character increases as:                 \[Li<Na<K<Rb<Cs\] Hence, \[LiF\] is the most stable compound.
