Naming Cycloalkanes Step 1-Find the parent by counting carbon atoms Named as alkyl-substituted cycloalkane The number of carbon atoms in the ring is equal to or greater than the number in the substituent Named as cycloalkyl-substituted alkane The number of carbon atoms in the largest substituent is greater than the number in the ring CH3 CH2CH2CH2CH3 3 carbons 4 carbons Methylcyclopentane 1-CyclopropylbutaneNamed as alkyl-substituted cycloalkane ▪ The number of carbon atoms in the ring is equal to or greater than the number in the substituent Named as cycloalkyl-substituted alkane ▪ The number of carbon atoms in the largest substituent is greater than the number in the ring Step 1 – Find the parent by counting carbon atoms Naming Cycloalkanes
