(a)
Interpretation:
The name of the cycloalkane has to be identified.
Concept Introduction:
Naming of Cycloalkane using
Cycloalkanes are named by adding cyclo- as a prefix to the name of the alkane corresponding to the number of carbons in the ring. Cycloalkanes-containing groups attached to the main ring are named the same way as branches in an alkane are. The positions of the substituent groups on the ring are identified by numbering the carbons in the chain so that the substituents have the lowest possible set of position numbers.
Use the Cycloalkane name as the parent.
Cycloalkanes are named as alkyl-substituted cycloalkanes rather than as cycloalkyl-substituted
Identify and number the substituents.
The group which has alphabetical priority should be numbered first and proceed around the ring in a direction in which the second substituent gets the lowest possible number.
(b)
Interpretation:
The name of the cycloalkane has to be identified.
Concept introduction:
Naming of Cycloalkane using IUPAC nomenclature:
Cycloalkanes are named by adding cyclo- as a prefix to the name of the alkane corresponding to the number of carbons in the ring. Cycloalkanes-containing groups attached to the main ring are named the same way as branches in an alkane are. The positions of the substituent groups on the ring are identified by numbering the carbons in the chain so that the substituents have the lowest possible set of position numbers.
Use the Cycloalkane name as the parent.
Cycloalkanes are named as alkyl-substituted cycloalkanes rather than as cycloalkyl-substituted alkanes. There is no need to assign a number if there is one substituent on the ring.
Identify and number the substituents.
The group which has alphabetical priority should be numbered first and proceed around the ring in a direction in which the second substituent gets the lowest possible number.
