Substituted Cyclic Compounds

  • If the number of carbon in the closed chain is greater or equal to the no. of carbon in an open saturated chain, then the closed chain will be selected as the parent chain.

  • If the number of carbon in the open-chain is greater than that of the closed chain, then the open-chain is a parent chain.

  • We consider the parent chain to the Cyclic compounds with a functional group.
