Question

In its nucleophilic substitution reaction, aryl halide resembles:

• A. vinyl chloride
• B. allyl chloride
• C. benzyl chloride
• D. ethyl chloride

Answer 1

The correct option is A vinyl chloride

Nucleophilic substitution occurs readily only when electron-withdrawing groups are present at suitable positions.

An aryl halide or a vinyl halide are electron-withdrawing groups, i.e nucleophiles, and nucleophiles cannot be attacked by a nucleophile, and are more prone to electrophilic reactions than nucleophilic reactions.

In vinyl and aryl halides you have an electron-rich pi cloud which can be seen a cloud of negative charge about the C-C bonds.

Hence, the correct option is $A$
