Concept explainers
a.
Interpretation:
The reason why the IUPAC name of the compound 3-methylbutane is incorrect has to be explained and correct IUPAC name for it has to be provided.
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:
- The longest chain in the compound has to be selected and it is known as parent name. The parent name represents the number of carbon atom present in the continuous carbon chain. The root name for
alkane compound is –ane. The single bonds are formed in alkane compounds. - The suffix group denotes the
functional group present in a molecule. The prefix group indicates the identity, location and number of substituents attached to the carbon compound. - Then name and number the substituents present in compounds. Then use prefix di-to represent two groups, tri- refers to three groups and so on.
- For cyclic structure: 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.
Interpretation
