a) 1-ethyl-3-methylcyclopentane b) 1,1,4-trimethylcyclohexane
Work Step by Step
a) There is a pentane ring and one ethyl and one methyl. The ethyl has priority over the methyl so it is named first. b) There is a hexane ring and three methyl groups. The two methyl group attached to the same carbon have priority since we want to have the lowest number naming.
