Hydrocarbons - Reaction Mechanism

Hydrocarbons are organic compounds that are entirely made up of only two kinds of atoms – carbon and hydrogen. Typically, hydrocarbons are colourless gases that have very weak odours.

Mechanism of electrophilic substitution reactions:

According to experimental evidences, SE (S = substitution; E = electrophilic) reactions are supposed to proceed via the following three steps:

  1. Generation of the electrophile
  2. Formation of carbocation intermediate
  3. Removal of proton from the carbocation interm
