Bromination of cyclopentane
WebRadical Halogenation. Alkanes (the simplest of all organic compounds) undergo very few reactions. One of these reactions is halogenation, or the substitution of a single hydrogen on the alkane for a single halogen (Cl 2 or Br 2) to form a haloalkane. This reaction is very important in organic chemistry because it functionalizes alkanes which ... WebQuestion: Explain why radical bromination of p-xylene forms C rather than D.
