Which one of the following compounds is different from the rest in terms of undergoing hydrolysis to form simpler compounds?

Options

A. Sucrose
B. Maltose
C. Lactose
D. Glucose

Answer

To solve the question of which compound is different from the rest in terms of undergoing hydrolysis to form simpler compounds, we can follow these steps:

### Step 1: Identify the Compounds
The compounds given in the question are:
- Sucrose
- Maltose
- Lactose
- Glucose

### Step 2: Classify the Compounds
- **Sucrose**, **Maltose**, and **Lactose** are disaccharides. They are composed of two monosaccharide units linked together.
- **Glucose** is a monosaccharide. It is the simplest form of sugar and cannot be broken down further.

### Step 3: Understand Hydrolysis
Hydrolysis is a chemical reaction that involves the breaking of a bond in a compound by the addition of water. In the case of carbohydrates:
- Disaccharides can be hydrolyzed into their constituent monosaccharides.
- Monosaccharides cannot be hydrolyzed further since they are already in their simplest form.

### Step 4: Analyze Hydrolysis of Each Compound
- **Sucrose** hydrolyzes to form glucose and fructose.
- **Maltose** hydrolyzes to form two glucose molecules.
- **Lactose** hydrolyzes to form glucose and galactose.
- **Glucose** does not undergo hydrolysis as it is already a monosaccharide.

### Step 5: Determine the Odd One Out
From the analysis:
- Sucrose, Maltose, and Lactose can all be hydrolyzed to form simpler compounds (monosaccharides).
- Glucose cannot be hydrolyzed further.

### Conclusion
The compound that is different from the rest in terms of undergoing hydrolysis to form simpler compounds is **Glucose**.
