Question

Why vinyl chloride is less reactive than ethyl chloride towards nucleophilic substitution reaction?

Answer 1

Explanation:

Why vinyl chloride is less reactive than ethyl chloride towards nucleophilic substitution reaction?

Answer 2

Vinyl Chloride is less reactive than ethyl chloride towards nucleophilic reaction because of resonance.

• When vinyl chloride undergoes resonance, the carbon chloride bond is converted into double bonds which decreases the reactivity.
• This is occurring because the lone pairs present in the chlorine atoms undergo resonance with the carbon-carbon bond due to which there is the formation of a partial carbon-chloride bond.
• Whereas ethyl chloride has a single bond, it is easier to break the bonds in the nucleophilic reaction and difficult to break the double bonds present in the vinyl chloride.
