Question

what is the iupac name for the following cyclic alkane? 1 - ethyl - 3 - propyl - 5 - methylcyclohexane 1 - butyl - 5 - propyl - 3 - methylcyclohexane 1 - butyl - 5 - methyl - 3 - propylcyclohexane 1 - ethyl - 3 - methyl - 5 - propylcyclohexane 1 - butyl - 3 - methyl - 5 - propylcyclohexane

Explanation:

Step1: Identify parent - ring

The parent - ring is cyclohexane as it is a six - membered cyclic alkane.

Step2: Identify substituents

There is a methyl group ($-CH_3$), an ethyl group ($-CH_2CH_3$), and a propyl group ($-CH_2CH_2CH_3$).

Step3: Number the ring

We number the ring in such a way that the substituents get the lowest possible numbers. Starting from the carbon with the ethyl group and numbering in a way to keep the numbers low for all substituents, we get the positions 1 - ethyl, 3 - propyl, 5 - methyl.

Answer:

1 - ethyl - 3 - propyl - 5 - methylcyclohexane
