Problem

Which of the following bonds is the least polar covalent (but not non-polar covalent bond)?

a. O - O

b. O - F

c. I - F

d. Br - F

e. Na - F

Solution

We’re being asked to determine which among the given covalent bonds is the least polar (but not non-polar). A covalent bond is formed by the sharing of electrons by two non-metals.


Recall that for a covalent bond to be:

• Polar: electronegativity difference must be greater than 0.5

• Non-polar: electronegativity difference must be less than 0.5


The lower the electronegativity difference, the less polar a bond is.
