I have always been confuse by this can somebody help me.

Which of the following is more likely and ionic compound?

a. NO
b. HI
c. ClF

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.
