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:
- Generation of the electrophile
- Formation of carbocation intermediate
- Removal of proton from the carbocation interm
