Explain why SN2 reactions on allyl bromide proceed faster than corresponding reactions on ethyl bromide.
Allyl Bromide
A halogenated compound (C3H5Br), often used as a building block in organic synthesis for introducing allyl groups.
Ethyl Bromide
A colorless, volatile compound used primarily in organic synthesis and as a fumigant; it is an alkyl halide with the formula C2H5Br.

Final Answer :
When the substrate is allylic, resonance stabilization through conjugation with the adjacent π bond occurs in the transition state. This delocalization lowers the energy of the transition state and results in an enhanced rate.
