The bond having the highest bond energy is : — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Step 1: Bond energy is influenced by bond order, atomic size (overlap efficiency), and bond polarity. Step 2: Oxygen is highly electronegative (3.5) and small, which results in highly effective 2p-2p orbital overlap and a strongly polar covalent character in the C=O double bond. Step 3: The combination of strong orbital overlap and electrostatic attraction from high polarity makes the carbonyl double bond (C=O) exceptionally strong and high in bond energy compared to C=C, C=S, and P=N. Thus, option (c) is correct.
