The two functional groups present in a typical carbohydrate are :

Options

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

Explanation

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

### Step 1: Understand the Structure of Carbohydrates
Carbohydrates are organic compounds that typically consist of carbon (C), hydrogen (H), and oxygen (O) atoms. They can be classified into simple sugars (monosaccharides) and complex carbohydrates (polysaccharides).

### Step 2: Identify Functional Groups in Carbohydrates
Carbohydrates can be categorized based on their functional groups. The two primary functional groups found in carbohydrates are:
1. **Carbonyl Group (C=O)**: This can be in the form of an aldehyde (when the carbonyl group is at the end of the carbon chain) or a ketone (when the carbonyl group is within the carbon chain).
2. **Hydroxyl Group (-OH)**: This group is present in all carbohydrates and contributes to their solubility in water.

### Step 3: Confirm the Presence of These Groups
When carbohydrates undergo hydrolysis, they can yield either aldehydes or ketones, confirming the presence of the carbonyl group. Additionally, the presence of multiple hydroxyl groups (polyhydroxy) is a characteristic feature of carbohydrates.

### Conclusion
Thus, the two functional groups present in a typical carbohydrate are:
- Carbonyl group (either aldehyde or ketone)
- Hydroxyl group

Therefore, the correct answer is **Option B: Carbonyl and Hydroxyl groups**.
