Types of Organic Reactions

There are four main types of organic reactions:

(1)   Substitution Reactions

Example: CH₄ + Cl₂ →CH₃Cl + HCl

(2)   Addition Reactions

 

Example: CH₂=CH₂ + Br₂ → BrCH₂CH₂Br

(3)   Elimination Reactions:

Example: BrCH₂CH₂Br + Zn → CH₂=CH₂ + ZnBr₂

(4)   Rearrangement Reactions:

Example: R-CH(Cl)-CH=CH₂ → R-CH=CH-CH₂(Cl)
