2. 4-isopropyl-1,5-dimethylcyclohexane

3. 1-isopropyl-2,4-dimethylcyclohexane

4. 4-isopropyl-1,3-dimethylcyclohexane

5. 1-isopropyl-4,6-dimethylcyclohexane

Final Answer:

The IUPAC name of the given compound is 1-isopropyl-4,6-dimethylcyclohexane.

Explanation:

The IUPAC name of a compound is determined by following a set of rules defined by the International Union of Pure and Applied Chemistry (IUPAC). In this case, the compound is a cyclic hydrocarbon with substituents. Let's break down the name step by step:

1. **Parent Chain**: The compound is a cyclohexane ring, and the longest continuous chain of carbons is 6, making it a cyclohexane. This serves as the parent chain.

2. **Substituents**: There are two substituents attached to the cyclohexane ring. The first substituent is an isopropyl group (a branched alkyl group) attached at position 1 of the cyclohexane ring. The second substituent is a dimethyl group, which is attached at positions 4 and 6 of the cyclohexane ring.

3. **Numbering**: The numbering of the cyclohexane ring starts from one of the substituents, which is the isopropyl group. This gives us the positions of the other substituents, which are 4 and 6.

4. **Name Order**: According to the IUPAC rules, substituents are listed alphabetically. The prefixes "1-isopropyl" and "4,6-dimethyl" are used to indicate the positions and nature of the substituents on the cyclohexane ring.

Combining all these elements, we get the IUPAC name **1-isopropyl-4,6-dimethylcyclohexane** for the given compound.
