IUPAC nomenclature of the given organic compound `(CH_(3))_(2)C(CH_(2)CH_(3))CH_(2)CH(Cl)CH_(3)` will be

Options

A. 5-Chloro-3,3-dimethylhexane
B. 4-Chloro-2-ethyl-2-methylpentane
C. 2-Chloro-4-ethyl-4methylpentane
D. 2-Chloro-4,4-dimethylhexane.

Explanation

To determine the IUPAC name of the organic compound `(CH₃)₂C(CH₂CH₃)CH₂CH(Cl)CH₃`, we will follow these steps:

### Step 1: Identify the Structure
First, we need to draw the structure of the compound based on the given formula. The compound can be represented as follows:

- There are two methyl groups (CH₃) attached to a carbon (C).
- This carbon is further connected to another carbon that has an ethyl group (CH₂CH₃).
- Continuing from this carbon, there are two more carbon atoms leading to a carbon that has a chlorine (Cl) substituent and a terminal methyl group (CH₃).

### Step 2: Determine the Longest Carbon Chain
Next, we need to identify the longest continuous carbon chain in the structure.

- Counting the carbon atoms, we find that the longest chain consists of 6 carbon atoms.

### Step 3: Number the Carbon Chain
We will number the carbon chain starting from the end closest to the substituents (in this case, the chlorine atom):

1. C1 - CH₃ (methyl)
2. C2 - CH₂ (next carbon)
3. C3 - CH (this carbon has a chlorine substituent)
4. C4 - CH₂ (next carbon)
5. C5 - C (this carbon is connected to two methyl groups)
6. C6 - CH₂CH₃ (ethyl group)

### Step 4: Identify and Name the Substituents
Now we identify the substituents on the longest chain:

- There are two methyl groups on C4 (4,4-dimethyl).
- There is one chlorine substituent on C2 (2-chloro).

### Step 5: Assemble the Name
According to IUPAC nomenclature rules, we list the substituents in alphabetical order and include their positions:

- The name will be structured as follows: [substituent] + [longest chain name].
- The longest chain is a hexane (6 carbons), so we will use "hexane".
- The substituents are 2-chloro and 4,4-dimethyl.

Putting it all together, the IUPAC name of the compound is **2-chloro-4,4-dimethylhexane**.

### Final Answer
The IUPAC name of the given organic compound `(CH₃)₂C(CH₂CH₃)CH₂CH(Cl)CH₃` is **2-chloro-4,4-dimethylhexane**.
