Which of the following statements is/are correct regarding the differences between the carbon-haloge — Haloalkanes and Haloarenes Chemistry Question

💡 Solution & Explanation

A) True; the lone pair on the halogen atom is in conjugation with the pi system of the benzene ring, generating partial double bond character via resonance. B) True; the partial double bond character and electron-rich aromatic ring in haloarenes strongly repel approaching nucleophiles, making typical $S_N1$ and $S_N2$ substitutions extremely difficult compared to haloalkanes. C) True; $sp^2$ carbons have greater s-character (33%) than $sp^3$ carbons (25%), making them more electronegative and shortening the C-X bond, increasing its strength. D) False; the dipole moment of chlorobenzene (1.69 D) is actually lower than that of cyclohexyl chloride (2.05 D). The $sp^2$ hybridized carbon pulls electron density towards itself, countering the C-Cl inductive effect, and the C-Cl bond is shorter.
