How many carbon atoms does Isobutyl chloride have in its present carbon chain ?

Options

A. n-Butyl alcohol
B. sec-Butyl alcohol
C. Isobutyl alcohol
D. tert-Butyl alcohol

Answer

To determine how many carbon atoms are present in the carbon chain of isobutyl chloride, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Structure of Isobutyl Chloride**:
- Isobutyl chloride is an alkyl halide derived from isobutane. Its chemical structure can be represented as follows:
```
CH3
|
CH3-C-CL
|
H
```
- In this structure, you can see that there are branches.

2. **Count the Carbon Atoms**:
- In the structure of isobutyl chloride, we can count the carbon atoms:
- There is one carbon atom in the central position (the one bonded to chlorine).
- There are two carbon atoms in the two methyl groups (CH3) attached to the central carbon.
- Therefore, the total number of carbon atoms is:
- 1 (central carbon) + 2 (from the two methyl groups) = 3 carbon atoms.

3. **Identify the Parent Chain**:
- The parent chain for isobutyl chloride is propane, which contains three carbon atoms in total.
- The name "isobutyl" indicates that it is a branched form of butane, specifically isobutane, which also has three carbon atoms.

### Final Answer:
Isobutyl chloride has **3 carbon atoms** in its carbon chain.
