In a polar, covalent bond, why might one area of a molecule be more negative than other areas of the molecule?

AThe atoms transfer electrons; therefore, that atom lost its electrons.

BThe atoms share electrons, but the electrons spend less time around that area of the molecule.

CThe atoms share electrons, but the electrons spend more time around that area of the molecule.

DThe atoms transfer electrons; therefore, that atom gained extra electrons.

Answer:

C. The atoms share electrons, but the electrons spend more time around that area of the molecule.

Explanation:

In a polar covalent bond between two non-metals electrons are shared. The two non-metals in the covalent bond have a difference in electronegativity. The atom with higher electronegativity attracts the shared pair of electrons more towards itself thus gaining a partial negative charge, and the other atom in the bond gains a partial positive charge.
