$1$. Acyclic or Open chain compounds $(I)$
$2$. Cyclic or Closed chain or Ring compounds $(II)$
Cyclic compounds are further classified into:
$1$. Homocyclic or Carbocyclic compounds
$2$. Heterocyclic compounds
Homocyclic or Carbocyclic compounds are further divided into:
$1$. Alicyclic compounds
$2$. Aromatic compounds (which are further classified into Benzenoid and Non-benzenoid compounds).
