On hydrolysis , which produces only glucose

Options

A. Galactose
B. maltose
C. Sucrose
D. None

Explanation

To determine which compound, upon hydrolysis, produces only glucose, we can analyze the hydrolysis of disaccharides and polysaccharides.

### Step-by-Step Solution:

1. **Identify the Compound**:
We need to identify a disaccharide or polysaccharide that, when hydrolyzed, yields only glucose. A common example of a disaccharide is maltose, which has the formula C12H22O11.

2. **Understand Hydrolysis**:
Hydrolysis is a chemical reaction involving the breaking of a bond in a molecule using water. In the case of disaccharides, hydrolysis typically breaks the glycosidic bond between two monosaccharides.

3. **Hydrolysis of Maltose**:
When maltose (C12H22O11) undergoes hydrolysis in the presence of water (H2O), it breaks down into two molecules of glucose (C6H12O6):
\[ C_{12}H_{22}O_{11} + H_2O \rightarrow 2 C_6H_{12}O_6 \]
This reaction shows that maltose produces only glucose upon hydrolysis.

4. **Conclusion**:
Therefore, the compound that produces only glucose upon hydrolysis is maltose.

### Final Answer:
On hydrolysis, maltose (C12H22O11) produces only glucose (C6H12O6).
