2. Master in Types Of Organic Reaction

Important types of organic reaction are as follow

• Additional Reaction : In this type of reaction a molecule or a group of molecules of reactant is added to a molecule connected by a double or triple bond. During this reaction a bond is formed from the double to single bond and triple bond to double bond or single bond is formed.
  CH₂ = CH₂ + Br₂ CH₂Br.CH₂Br
  ethylene 1:2 dibromo ethane
  
• Substitution Reactions : In this type of reaction the molecular/group attached to the carbon atom is displaced by another molecular/group.
  C₆H₅ → C₆H₅NO₂
  Benzene nitrobenzene
  
• Elimination Reaction : In this type of reaction two molecule or groups attached to carbon atoms are removed without being displaced by other molecules or groups.
  
• Rearrangement Reaction : During this type of reaction , a molecule or group of molecule is transferred from one molecule to another molecule in the same molecule
