검증된 단계별 안내1
Identify the carbon atom in acetic acid that is bonded to two oxygen atoms. This is the carbonyl carbon (the carbon in the carboxyl group, -COOH).
Determine the types of bonds around this carbon. It forms a double bond with one oxygen (carbonyl oxygen) and a single bond with the other oxygen (hydroxyl oxygen), as well as a single bond with a carbon or hydrogen atom.
Count the regions of electron density (bonding and lone pairs) around this carbon. The carbonyl carbon has three regions of electron density: one double bond and two single bonds.
Recall that the hybridization corresponds to the number of electron density regions: three regions correspond to sp\(\textsuperscript{2}\) hybridization.
Conclude that the carbon atom bonded to two oxygen atoms in acetic acid is sp\(\textsuperscript{2}\) hybridized.
