Which is the IUPAC name of `CH_(3) - overset(C_(2)H_(6))overset(|)underset(C_(2)H_(6))underset(|)C-CH_(2)Cl`

Explanation

To determine the IUPAC name of the compound `CH₃ - C₂H₆ | C₂H₆ | C - CH₂Cl`, we will follow these steps:

### Step 1: Draw the Structure
First, let's visualize the structure of the compound. The given formula suggests a branched alkane with a chlorine substituent. We can expand it to see the arrangement of carbon atoms and substituents.

### Step 2: Identify the Longest Carbon Chain
We need to identify the longest continuous carbon chain in the structure. The longest chain will determine the base name of the compound. Count the carbon atoms in various possible chains and select the longest one.

### Step 3: Number the Carbon Chain
Once the longest chain is identified, we need to number the carbon atoms in the chain. The numbering should start from the end closest to the substituent (in this case, the chlorine atom).

### Step 4: Identify and Name the Substituents
Next, we identify the substituents attached to the main carbon chain. In this case, we have:
- A chlorine atom (Cl)
- Ethyl groups (C₂H₅)
- Methyl groups (CH₃)

### Step 5: Assign Locants to Substituents
Assign locants (numbers) to each substituent based on their position on the carbon chain. The locants should be the lowest possible numbers.

### Step 6: Write the IUPAC Name
Now, we can write the IUPAC name. The substituents are listed in alphabetical order, and their locants are included. The base name is derived from the longest carbon chain.

### Final IUPAC Name
Based on the above steps, the IUPAC name of the compound is **1-Chloro-2-ethyl-2-methylbutane**.
