What will be the IUPAC name of the given compound-
`CH_(3) - underset(CH_(2) -CH_(3))underset(|)CH-overset(CH_(3))overset(|)CH-CH_(2)-overset(CH_(2)-CH_(3))underset(|)(CH)-CH_(3)`

Explanation

To determine the IUPAC name of the given compound, we will follow these steps:

### Step 1: Identify the Longest Carbon Chain
First, we need to identify the longest continuous carbon chain in the compound. Count the number of carbon atoms in the chain.

- In the given compound, the longest chain consists of **8 carbon atoms**.

### Step 2: Number the Carbon Chain
Next, we will number the carbon chain. The numbering should be done in such a way that the substituents (methyl groups in this case) get the lowest possible numbers.

- Start numbering from the end of the chain that is closest to the first substituent.
- The chain can be numbered as follows:
1. C1
2. C2
3. C3
4. C4
5. C5
6. C6
7. C7
8. C8

### Step 3: Identify the Substituents
Now, identify the substituents attached to the main carbon chain.

- In this case, we have **three methyl groups** attached to the main chain.
- The positions of the methyl groups are at C3, C4, and C6.

### Step 4: Write the Name of the Compound
Now that we have the longest chain and the substituents identified, we can write the IUPAC name.

- The substituents are listed in alphabetical order, but since they are all methyl groups, we will use the prefix "tri-" to indicate that there are three methyl groups.
- The name will be structured as follows:
- The positions of the substituents: 3, 4, and 6.
- The substituent name: trimethyl.
- The parent chain name: octane (since there are 8 carbon atoms).

Thus, the IUPAC name of the compound is **3,4,6-trimethyloctane**.

### Final Answer:
**3,4,6-trimethyloctane**
