D

Verified step by step guidance1
Understand that a covalent bond involves the sharing of electrons between atoms.
Recognize that when electrons are shared equally, the bond is called a nonpolar covalent bond.
Identify that when electrons are shared unequally, one atom attracts the electrons more strongly, creating a partial positive and partial negative charge.
This unequal sharing of electrons results in a dipole moment, meaning the molecule has a positive end and a negative end.
The term for this type of bond, where electrons are shared unequally and a dipole moment exists, is a polar covalent bond.
