Work Step by Step
We have to follow the following steps step1: Name the parent cycloalkane. step2: Identify the substituents. step3: Number the substituents in a manner such that the second substituent receives the lowest possible number. step4: Name the compound, and if two different alkyl groups are present then place them alphabetically. Thus the required compound name is 3-Ethyl-1, 1-dimethylcyclopentane.
