Give the IUPAC name of `m-ClCH_(2)C_(6)H_(4)CH_(2)C(CH_(3))_(3)`

Options

A. 1 - (3 - Chloro -3- methylphenyl) -2, 2 - diethyl propane
B. 2 - (3 - Chloromethyl propyl) - 2 , 2 - dimethyl propane
C. 1 - (3 - Chloromethyl phenyl) - 3, 3 - dimethyl propane
D. 1 - Chloromethyl -3 - (2, 2 - dimethyl propyl) benzene

Answer

To determine the IUPAC name of the compound `m-ClCH_(2)C_(6)H_(4)CH_(2)C(CH_(3))_(3)`, we will follow these steps:

### Step 1: Identify the Main Structure
The compound contains a benzene ring (C6H4) with a chloro group (Cl) and a propyl group (C(CH3)3) as substituents. The benzene ring will be the main structure.

**Hint:** Look for the longest continuous carbon chain that includes the functional groups.

### Step 2: Determine the Position of Substituents
The chloro group (Cl) is in the meta position relative to the other substituents on the benzene ring. The propyl group is attached to the benzene ring as well.

**Hint:** Use the numbering of the benzene ring to identify the position of substituents. Start numbering from the carbon attached to the chloro group.

### Step 3: Identify the Side Chains
The propyl group is a branched chain, specifically a tert-butyl group (C(CH3)3). The other substituent is a chloromethyl group (–CH2Cl).

**Hint:** Identify the substituents and their structures to name them correctly.

### Step 4: Number the Carbon Chain
Number the benzene ring starting from the carbon attached to the chloro group. The chloro group will be at position 1, and the tert-butyl group will be at position 3.

**Hint:** Ensure that the substituents receive the lowest possible numbers.

### Step 5: Write the Name in IUPAC Format
Combine the names of the substituents in alphabetical order with their respective positions. The chloro group is named first (1-chloro), followed by the tert-butyl group (3-tert-butyl), and then the benzene ring.

The final IUPAC name is:
**1-chloro-3-tert-butylbenzene**

### Summary of the Steps:
1. Identify the main structure (benzene).
2. Determine the position of substituents (meta position).
3. Identify the side chains (chloromethyl and tert-butyl).
4. Number the carbon chain appropriately.
5. Combine the names of substituents in the correct order.
