Verified step by step guidance

Identify the types of atoms involved in the bond: Carbon (C) and Oxygen (O).

Recall that a covalent bond involves the sharing of electrons between atoms.

Consider the electronegativity values of carbon and oxygen. Oxygen is more electronegative than carbon.

Understand that when there is a significant difference in electronegativity between two atoms, the shared electrons are more attracted to the more electronegative atom, creating a polar covalent bond.

Conclude that the bond between carbon and oxygen is a polar covalent bond due to the difference in electronegativity, where electrons are shared unequally.
