Which of the following accurately describes the bond energy and length of a carbonyl bond compared t — Aldehydes Ketones and Carboxylic Acids Chemistry Question

💡 Solution & Explanation

The carbonyl $C=O$ double bond is shorter ($1.23$ \AA) and significantly stronger ($178$ kcal/mol) than the standard alkene $C=C$ double bond ($1.33$ \AA, $146$ kcal/mol) due to the high electronegativity of oxygen, which imparts strong ionic character to the bond.
