The reactions of organic compounds can he classified into four main groups.
They are: Substitution, Addition, Elimination and Rearrangement.
Organic reactions are molecular type of reactions. Factors governing organic reactions are essentially the same as that of any chemical reaction.
Organic reactions depend on following factors:
(1) Functional group.
(ii) Presence of covalent bond (σ/π)
(iii) Nature of attacking reagent.
(iv) Environment (Acidic, basic or neutral) of reaction.
