ADDITION REACTION
-
-
-
MARKOUNIKOVS RULE
The addition of unsymmetrical reagents such as HX HO, HOX etc. to unsymmetrical alkene occurs in such a way that the negative part of the addendum goes to that carbon atom of the double bond which carries lesser member of hydrogen atom

-
ELIMINATION REACTION
-
SAYTZEFF'S RULE
The favored product in dehydrohalogenation reactions is the alkene with the greatest amount of alkyl groups connected to the doubly bound carbon atoms.”
-
-
-
Substitutions are initiated by free radical. The reaction takes place by a free radical chain mechanism.
-
-
-
-
-
involves the loss of halogen and the hydrogen atom from a carbon adjacent to the one losing the halogen (beta-elimination).
-
-
-
This reaction involve the replacement of an atom or a group of atoms present in the organic compound by the nucleophile.
-
-
a group or radical attached to a carbon atom is replaced by another atom or group of atoms called substituents.
This are initiated by the electrophilic reagents and involves the replacement of atom or a group of atoms present in the organic compound by the electrophile.
