Solution
The correct answer is D. The more electronegative atom will make its end of the bond more negative.
Here's why:
Electronegativity is a measure of the ability of an atom to attract electrons. When two atoms form a bond, the atom with the higher electronegativity will have a greater pull on the shared electrons. This means that the electrons will spend more time closer to the more electronegative atom, giving it a partial negative charge. The other atom, which has a lower electronegativity and therefore a lesser pull on the electrons, will have a partial positive charge. This distribution of charge creates a polar bond, with the more electronegative atom forming the negative end of the bond.
