The two function groups present in a typical carbohydrate are

Options

A. `-OH and -COOH`
B. `-CHO and -COOH`
C. `gt C = O and -OH`
D. `-OH and -CHO`

Answer

To solve the question regarding the two functional groups present in a typical carbohydrate, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Carbohydrates**:
- Carbohydrates are organic compounds that typically consist of carbon (C), hydrogen (H), and oxygen (O). They are classified into different types based on their structure.

2. **Identifying Functional Groups**:
- The main functional groups found in carbohydrates are:
- **Aldehyde group (CHO)**: This is present in carbohydrates known as aldoses.
- **Ketone group (C=O)**: This is present in carbohydrates known as ketoses.
- Additionally, carbohydrates contain multiple hydroxyl groups (-OH), which are characteristic of their polyhydroxy nature.

3. **Analyzing the Options**:
- Now let's evaluate the options provided in the question:
- **Option A**: OH and COOH - This option is incorrect because while OH is present, COOH (carboxylic acid) is not a typical functional group in carbohydrates.
- **Option B**: CHO and COOH - This option is also incorrect because COOH is not a standard functional group in carbohydrates.
- **Option C**: Ketone and OH - This option is correct as it includes the ketone functional group and the hydroxyl group.
- **Option D**: OH and CHO - This option is also correct as it includes the hydroxyl group and the aldehyde functional group.

4. **Conclusion**:
- The two functional groups present in a typical carbohydrate are:
- **CHO (aldehyde group)** and **OH (hydroxyl group)** for aldoses.
- **C=O (ketone group)** and **OH (hydroxyl group)** for ketoses.
- Therefore, the correct answers are **Option C (Ketone and OH)** and **Option D (OH and CHO)**.

### Final Answer:
The two functional groups present in a typical carbohydrate are **CHO (aldehyde)** and **OH (hydroxyl)**, or **C=O (ketone)** and **OH (hydroxyl)**.
