Answer 1

IUPAC NOMENCLATURE

* Naming in open chain saturated hydrocarbon-

1. longest chain is selected as a parent carbon chain with maximum number of substituent.

2. Number the parent chain to define the location, position of multiple bond, functional group and side chain.

3. We number the parent carbon chain from the side which the side chain is nearer, known as locant rule and name the substituent and place them alphabetically order.

* Naming in cyclic componds.

1.Determine the parent chain: the parent chain contains the most carbon atoms.

2.Number the substituents of the chain so that the sum of the numbers is the lowest possible .

3.Name the substituents and place them in alphabetical order.

4. If stereochemistry of the compound is shown, indicate the orientation as part of the nomenclature.
