ANSWER

Organic compounds are more reactive towards S

N

1, if the carbocation is stable compared to others.

Here, in allyl chloride ⇒CH

2

=CH−CH

2

−Cl the cation formed is CH

2

=CH−C

H

2

⊕

⇋C

H

2

⊕

−CH=CH

2

is stabilized by equivalent resonance. So, allyl chloride has high reactivity towards S

N

1.
