Nomenclature of cycloalkanes

IUPAC rules used for naming of cycloalkanes

• Name the parent cycloalkane
• Assign numbering to the substituents
• Assign the first number to the bulky group
• Halogens get the first priority
• Write the name of the molecule in alphabetic

Naming of cycloalkane

1. The parent cycloalkane is cyclopentane
2. The substituent that is methyl and ethyl
3. Position of both methyl is 1 and 3 for ethyl
4. So, the IUPAC name is 1,1 dimethyl 3-methyl cyclohexane
