Give the IUPAC name of `m - ClCh_2C_6H_4CH_2C(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 propyl) - 3, 3-dimethyl propane
D. 1 - Chloromethyl - 3- (2, 2 - dimethyl propyl) benezene

Answer

To determine the IUPAC name of the compound `m - ClCH2C6H4CH2C(CH3)3`, we will follow these steps:

### Step 1: Identify the Structure
We need to visualize the structure based on the given formula. The "m" indicates that the chlorine substituent is in the meta position on the benzene ring.

### Step 2: Draw the Benzene Ring
Start by drawing a benzene ring. Label the carbon atoms in the ring from 1 to 6.

### Step 3: Place the Substituents
- Place the `CH2Cl` group at position 1 (the meta position).
- The other substituent is `CH2C(CH3)3`, which is a tert-butyl group. This will be placed at position 3.

### Step 4: Number the Carbon Chain
The tert-butyl group can be broken down as follows:
- The `C(CH3)3` indicates that there are three methyl groups attached to a carbon atom.
- The full structure will look like this:
- At position 3, we have a `CH2` connected to a `C` that has three `CH3` groups.

### Step 5: Identify the Substituents
- The substituent at position 1 is `chloromethyl` (from `CH2Cl`).
- The substituent at position 3 is `tert-butyl`, which can be named as `2,2-dimethylpropyl` since it consists of a propyl group with two methyl groups attached to the second carbon.

### Step 6: Combine the Names
Now we can combine the names of the substituents with the base name of the benzene ring:
- The IUPAC name will be: **1-chloromethyl-3-(2,2-dimethylpropyl)benzene**.

### Final Answer
The IUPAC name of the compound is **1-chloromethyl-3-(2,2-dimethylpropyl)benzene**.
