Question

Resonance structure of molecule does not have

• A. Identical arrangement of atoms
• B. Nearly the same energy content
• C. The same number of paired electrons
• D. Identical bonding

Answer 1

The correct option is D Identical bonding

Resonance structure of a molecule does not have identical bonding. Resonance occurs due to delocalisation of π electrons. It is a phenomenon in which two or more structures involving identical positions of atoms, can be written for a particular compound. All other options except (d) are true regarding resonance.
