💡 Solution & Explanation

# Delocalization of Electrons and Molecular Stability **Understanding Delocalization:** Electron delocalization occurs when electrons spread over multiple atoms/orbitals rather than being localized between two atoms (as in a single bond). **Effect on Electrons-Nuclei Attraction:** When electrons delocalize: - They occupy a larger spatial region across multiple nuclei - Each nucleus can exert electrostatic attraction on the delocalized electrons - The effective attraction between the electron cloud and all nuclei in the system increases - This increased electrostatic attraction lowers the overall energy of the molecule **Why This Increases Stability:** $$\text{Greater electrons-nuclei attraction} \rightarrow \text{Lower potential energy} \rightarrow \text{More stable molecule}$$ **Evaluating Other Options:** - **(B)** False — electron-electron repulsion doesn't significantly decrease with delocalization - **(C)** False — potential energy *decreases* (not increases), which is why stability increases - **(D)** Partially correct outcome but incorrect reasoning (stability increases due to attraction, not just energy decrease) **Answer: (A)** — Delocalization increases molecular stability because electrons-nuclei attraction increases when electrons are distributed over multiple nuclei simultaneously.
