Determine the most polar covalent bond among the given choices. Recall that 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 higher the electronegativity difference, the more polar a bond is. Using the provided electronegativity values, find the EN difference
