Which of the following pairs of atoms would be most likely to form a polar covalent bond?

Question

Quizplus · Accepted Answer

The pair of atoms in option A, H and Cl, are the most likely to form a polar covalent bond. This is because Cl is more electronegative than H, which means it has a greater pull on the shared electrons in the bond. This results in a partial negative charge on the Cl atom and a partial positive charge on the H atom, making the bond polar. Options B, C, D, and E all involve pairs of atoms with similar electronegativities, which would result in a nonpolar covalent bond.
