Which of the following hydrocarbon contains maximum number of covalent bonds?

Options

A. `C_(3)H_(8)`
B. `C_(4)H_(6)`
C. `C_(4)H_(10)`
D. `C_(4)H_(8)`

Explanation

To determine which hydrocarbon contains the maximum number of covalent bonds, we will analyze the structures of the given hydrocarbons and count the covalent bonds in each.

### Step-by-Step Solution:

1. **Identify the Hydrocarbons**: Let's assume we have the following hydrocarbons:
- C3H8 (Propane)
- C4H10 (Butane)
- C4H8 (Butene)

2. **Draw the Structures**:
- **C3H8 (Propane)**: The structure is:
```
H H H
| | |
H-C-C-C-H
| | |
H H H
```
- Count the bonds: Each carbon forms 4 bonds, and there are 3 carbon atoms and 8 hydrogen atoms. The total number of covalent bonds is 10.

- **C4H10 (Butane)**: The structure is:
```
H H H H
| | | |
H-C-C-C-C-H
| | | |
H H H H
```
- Count the bonds: There are 4 carbon atoms and 10 hydrogen atoms. The total number of covalent bonds is 13.

- **C4H8 (Butene)**: The structure is:
```
H H H H
| | | |
H-C-C=C-C-H
| | | |
H H H H
```
- Count the bonds: There are 4 carbon atoms and 8 hydrogen atoms. The total number of covalent bonds is 12.

3. **Count the Total Covalent Bonds**:
- C3H8: 10 covalent bonds
- C4H10: 13 covalent bonds
- C4H8: 12 covalent bonds

4. **Determine the Maximum**:
- Comparing the total covalent bonds:
- C3H8: 10
- C4H10: 13
- C4H8: 12
- The hydrocarbon with the maximum number of covalent bonds is **C4H10 (Butane)** with 13 covalent bonds.

### Final Answer:
The hydrocarbon that contains the maximum number of covalent bonds is **C4H10 (Butane)**.
