Question

Arrange the following bonds in order of increasing polarity. (a) H — F, F — F, H — H, H — I

Answer 1

Answer:H-F>F-F>H-I>H-H

Explanation:The polarity of a bond is determined by the difference in electronegativity between the two atoms of the bond. Electronegativity is a measure of an atom's ability to attract electrons to it in a chemical bond. The greater the difference in electronegativity between two atoms, the more polar the bond.

The electronegativity values for the atoms:

H: 2.2

F: 3.98

I: 2.66
