Interpretation:
The structure of the organic compounds should be given.
Concept introduction:
Organic compounds are named systematically by using IUPAC rules.
Name of the organic compounds are given according to the number of carbon present in the molecule for example
A molecule having one carbon atom, the molecule name will start with meth etc.…
If any halogens are present in the molecule, the name of the halogens as follows.
Naming the substituted
