Step-by-Step Verified Solution
Because of high electronegativities of the
halogen atom, the carbon halogen (C � X) is highly
polarised covalent bond. Thus, the carbon atom
of the C � X bond becomes a good site for attack
by nucleophiles (electron rich species).
Nucleophilic substitution reactions are the most
common reactions of alkyl halides.
