    a. NO

    The answer is d. and I understand that part, but why is not also HI... I know is something to do with the hydrogen but exactly how it works.

    look at the differeces between electronagtivity of two atoms in your compands. if i remeber well it must be over 1.8, plus just remeber metal nonmetal are very common ionic componds.

    HI has a covalent bond not ionic.
