Why are organic compound found in larger no? or Why are they studied as a separate subject ?

Explanation

(i) Catenation Property : Carbon atom gas a property by which it can join with other C-atom and form a long chain or a ring of different size and shaped. If covalency of atom is more, then catenation property is also more.
(ii) Organic compound shows isomerism.
(iii) Exhibits Homologous Series.
(iv) Same Empirical Formulae.
(v) Polymerisation.
