JEE Main Chemistry question

Aryl halides are less reactive than alkyl halides towards nucleophilic substitution due to:

(A)ResonanceCorrect
(B)Stability of carbonium ions
(C)High boiling point
(D)None of the above

Answer: (A)

Solution

In an aryl halide, the halogen's lone pair is delocalised into the aromatic ring by resonance, giving the carbon–halogen bond partial double-bond character. This makes the bond stronger and shorter than a typical
