which nucliophilic substitution recation is showed by benzyl hallide and alylic hallide and why
Asked by sheetal | 09 Jan, 2013, 05:31: AM
answered-by-expert Expert Answer

Allyl chlorides, bromides and iodides are good substrates for nucleophilic substitution reactions.

Reaction type: Nucleophilic substitution (SN1 or SN2)
  • Benzylic halides undergo nucleophilic substitution reactions very readily
  • 1o benzylic halides typically react via an SN2 pathway , and there is no competition from elimination.
  • 2o or 3o benzylic halides typically react via an SN1 pathway , via the resonance stabilised carbocation.
