Question

According to established kinetic mechanisms, chlorobenzene and other specific aryl halides heavily containing electron-donating substituents strictly undergo nucleophilic substitution reactions utilizing which specific pathway?

Answer: D

💡 Solution & Explanation

Unactivated aryl halides like chlorobenzene, along with those physically possessing strictly electron-donating substituents, are chemically exceptionally inert towards direct nucleophilic attack. Under rigorously harsh basic conditions, they are strictly forced to react entirely via the high-energy elimination-addition pathway, definitively known as the benzyne mechanism.
