Which of the following molecules would contain a polar covalent bond? A molecule containing two atoms

of different elements with different electronegativities

Explanation:

A molecule containing two atoms "of different elements with different electronegativities"

A polar covalent bond exists when two different atoms (non-metals) with different electronegativities are able to share their electrons in a covalent bond.

Some examples of polar covalent bonds are seen in:

1. Ammonia(NH3): The polar covalent bonds exists between the nitrogen and hydrogen atoms.

2. Water(H2O): The polar covalent bond exists between hydrogen and oxygen. The oxygen molecule has a net negative charge while the hydrogen atoms have a net positive charge.
