Question

a covalent bond where there is unequal sharing of electron pairs is called a(n) ______ covalent bond.

o ionic
o polar
o nonpolar
o valence

Explanation:

In a polar covalent bond, there is unequal sharing of electron - pairs due to differences in electronegativity between the atoms involved. Ionic bonds involve transfer of electrons, non - polar covalent bonds have equal sharing of electrons, and valence refers to the combining capacity of an atom, not a type of bond with unequal electron - pair sharing.

Answer:

B. polar
