How does atom electronegativity affect bond character and molecular polarity?

Explanation:

Electronegativity is defined as the ability of an atom to attract electrons towards itself.

When atoms of a compound or molecule attain partial charges due to the difference in their electronegativity then it is known as molecular polarity.

More is the electronegativity of the combining atoms more ionic bond character the compound will have.

For example, HCl is an ionic compound.

Whereas less is the difference between electronegativity of combining atoms more covalent character the compound will have.

For example, is a covalent compound.
