Question: is carbon and oxygen a polar covalent bond

Answer: Yes, A carbon--oxygen bond is a polar covalent bond between carbon and oxygen. Oxygen has 6 valence electrons and prefers to either share two electrons in bonding with carbon, leaving the 4 nonbonding electrons in 2 lone pairs :O: or to share two pairs of electrons to form the carbonyl functional group. =O: Simple representatives of these two bond types are the OH in alcohols such as the ethanol in beverages and fuels and the C=O in ketones (as well as many other related carbonyl compounds).
