is there any formula for calculating the number of ring isomers and chain isomers for any organic compound? if yes then please answer it.

Dear Niranjan,

Organic chemistry mainly deals with hydrocarbons and their derivatives. Hydrocarbons are organic compound composed of carbon and hydrogen such as alkane, alkene and alkynes. While their derivatives may consist of other atoms like oxygen in ether, alcohol, sulfur in thiols etc.

Organic compounds are mainly exist in nature and are also synthesized by synthetic processes. They can be mainly classified in two types.

1. Open chain compounds and
2. Cyclic compounds

Open chain compounds or aliphatic compounds contain straight or branched chains of carbon atom skeleton with appropriate number of hydrogen atom and other functional groups. Cyclic compounds are composed of closed ring skeleton and can be heterocyclic contains atoms other than carbon or homocyclic contains only carbon atoms.

dear  AMAN

you have not answered my question properly.i was asking about a way to calculate the total number of isomers not about organic compound.

No. i am sorry that there is no such formula for calculation of isomers
