Explain, based on the Alkylbenzenes such as toluene (methylbenzene) react with NBS to give products in which bromine substitution has occurred at the position next to the aromatic ring Bond Dissociation Energies Bond dissociation energy is lowest for a C-H bond involving a tertiary carbon, indicating that it is easiest to cleave this C-H bond homolytically.

Explain, CiNii 国立情報学研究所 学術情報ナビゲータ [サイニィ] 詳細へ移動 検索フォームへ移動 The predominance of allylic substitution over other positions comes down to bond dissociation energies. This paper introduces additional methods during dissociation of gaseous One such reagent is N-bromosuccinimide (NBS), shown in the second equation below.
