NEETChemistryHaloalkanes and Haloarenes

Why are haloarenes less reactive than haloalkanes towards nucleophilic substitution reactions?

Options

  1. ADue to a shorter C—Cl bond
  2. BDue to a longer C—Cl bond
  3. CDue to a greater s-character of carbon in haloalkanes
  4. DDue to a lower s-character of carbon in haloalkanes

Correct answer

A. Due to a shorter C—Cl bond

Step-by-step solution

Haloarenes are less reactive than haloalkanes towards nucleophilic substitution reactions because of the difficulty in breaking a shorter C—Cl bond in haloarenes.
