Sucrose contains which of the following groups

Options

A. `-CHO`
B. ` gt C=O`
C. both (a) and (b)
D. none of these

Answer

To determine which groups are present in sucrose, we can follow these steps:

### Step 1: Understand the Structure of Sucrose
- Sucrose is a disaccharide composed of two monosaccharides: glucose and fructose.

### Step 2: Identify the Functional Groups in Sucrose
- Glucose is an aldose, which means it contains an aldehyde group (–CHO).
- Fructose is a ketose, which means it contains a ketone group (–CO).

### Step 3: Analyze the Composition of Sucrose
- Since sucrose is formed by the combination of glucose and fructose, it retains the characteristics of both sugars.
- Therefore, sucrose contains both an aldehyde group from glucose and a ketone group from fructose.

### Step 4: Conclusion
- Based on the presence of these functional groups, we can conclude that sucrose contains both CHO (aldehyde) and CO (ketone) groups.

### Final Answer
- Sucrose contains both CHO and CO groups.
