Question

Standard aryl halides are universally fundamentally considered severely vastly less chemically reactive strictly towards bimolecular nucleophilic substitution ($S_N2$) directly compared to standard alkyl halides. What is the explicit dominant reason?

Answer: B

💡 Solution & Explanation

In standard haloarenes, the active non-bonding lone pairs explicitly present on the halogen atom smoothly natively partake in $+M$ resonance with the adjacent $\pi$ system, heavily imparting strong partial double bond character that heavily natively strengthens the bond.
