In a polar covalent bond, the distribution of common electrons are
a). not shared evenly due to a greater positive charge from one atom’s nucleus
b). pulled more strongly toward the smaller atom
c). shared evenly between the two atoms
d). taken completely by the more electronegative atom

I think the correct answer from the choices listed above the first option. In a polar covalent bond, the distribution of common electrons are not shared evenly due to a greater positive charge from one atom’s nucleus. Hope this answers the question.

A.) Not shared evenly due to a greater positive charge from one atom's nucleus.
