2-ethyl-1,3-dimethylcyclopentane
The cyclopentane is the parent; the lowest number sequence is generated when the methyl group is bonded to carbon #1, proceeding clockwise.
5-bromo-5-ethyl-2-methylnonane
The nonane is the parent; the lowest number sequence is generated when the methyl group is bonded to carbon #2.
2,5-diethyl-1,1-dimethylcyclohexane
The cyclohexane is the parent; the lowest number sequence is generated when the geminal dimethyl group is bonded to carbon #1, proceeding counter-clockwise.
