What Results from an Unequal Sharing of Electrons Between Atoms

Question

What results from an unequal sharing of electrons between atoms?
A) a nonpolar covalent bond
B) a polar covalent bond
C) an ionic bond
D) a hydrogen bond
E) a hydrophobic interaction

Accepted Answer

Unequal sharing of electrons between atoms results in a polar covalent bond, where one atom has a partial negative charge and one has a partial positive charge. This occurs when the electronegativity (ability to attract electrons) of the two atoms involved in the bond is not equal.
