Which of the following bonds is a polar covalent bond?
A)Na-F
B)C-H
C)C-O
D)Cl-Cl

Question

Quizplus · Accepted Answer

The covalent bond between C and O is polar because oxygen is more electronegative than carbon, causing the shared electrons to be more attracted to the oxygen atom, resulting in a partial negative charge on the oxygen and a partial positive charge on the carbon. The other options either have purely ionic bonds (A) or nonpolar covalent bonds (B and D).
