    If the bond forming entities are dissimilar with different electronegativity. The bond formed has partial ionic character as the electron pair is attracted by more electronegativity. Such a bond is called polar covalent bond. Which of the following have lowest degree of covalency?

    A)  NaCl               

    B)  \[MgC{{l}_{2}}\]

    C)  AgCl               

    D)  CsCl

    Correct Answer: D

    Solution :

    Higher the electronegativity difference, lower is its degree of covalency. Here CsCl has highest electronegativity difference hence lowest degree of covalency.
