Concept explainers
a.
Interpretation:
The structure of given compound propylcyclopentane has to be drawn.
Concept Introduction:
The system which is used to name an organic compound is known as IUPAC Nomenclature. IUPAC are known as International Union of Pure and Applied Chemistry.
There are some rules followed for writing IUPAC Nomenclature for cycloalkane compounds:
- First identify the number of carbon atoms present in the ring. The numbers of carbon atoms present in ring is used as the parent name. Add suffix name -ane and prefix name cyclo- to the parent name of cycloalkane compound.
- The suffix group denotes the
functional group present in a molecule. Then number the substituents present in compound. If there is a single substituent no need to mention number. If the ring has more than one substituent, then start numbering the ring with lowest number to the substituents in alphabetical order. Hence combine the parts to form IUPAC name.
b.

The structure of given name 1,2-dimethylcyclobutane has to be explained.
Concept Introduction:
