Organic compound

 Organic compound

The Study of compound of carbon and hydrogen and,their derivatives is,called organic compound.
 Classification of organic compound

 (i) Open chain or Alicylic compound 
(ii) Closed chain or cylic compound

 Open chain or Alicyclic chain

                                               The compound in which first and last carbon are not directly linked with each other. It is also called aliphatic compound.

 Straight chain (or non branched ) compound 

                                                                     Those organic compound in which the carbon atoms are connected in series from one to the other. 

 For example

n butane 

Branched chain compound 

                                           Those organic compound in which the,carbon atoms are attached in a series as well as along the side of chain.

  For example

 Isobutylene

 Close chain compound or Cylic compound 

                                                                     The compound in which the first and the last carbon are directly joined with each other.

 a) Homocyclic or carbocyclic compound 

                                                                The compound which the ring consists of only carbon atoms .

 Homocyclic compound are further classified as

 I)Alicyclic compounds 
II) Aromatic compounds

 Alicyclic Compound

The homocyclic compound in which ring consist of three or more carbon atomand resembling aliphatic compounds are called alicyclic compound.

 Formula

 CnH2n 

 Example

 Cyclopropane

 2)Aromatic compound

 The compound in which ring consist of benzene ring , six carbon atom with three alternate double and single bonds.

 Example 

 Benzene 
The aromatic compound may have a side chain or a functional group attached to the ring.

 Example 

 Toluene 

The aromatic compound may also contain more than one benzene rings fused toghter. 

Example 

Naphthalene 

 B) Hetrocyclic Compounds

                                               The compound in which ring consist of more than one kind of atoms are,called hetrocgclic compound or hetrocycles.
 In hetrocyclic compound generally one or more atom of element such as nitrogen, oxygen, or sulphur are present .
 The atom other than carbon viz, N, O , S,present in the,ring is called a betero atom.
