When sucrose is heated with conc. `HNO_(3)` acid the product is

Options

A. Saccharic acid
B. Oxalic acid
C. Formic acid
D. Invert sugar

Answer

To determine the product formed when sucrose is heated with concentrated nitric acid (HNO3), we can follow these steps:

### Step-by-Step Solution:

1. **Identify Sucrose**:
Sucrose is a disaccharide composed of glucose and fructose. Its chemical formula is C12H22O11.

2. **Understand the Reaction**:
Concentrated nitric acid (HNO3) acts as an oxidizing agent. When sucrose is heated with HNO3, it undergoes oxidation.

3. **Oxidation Process**:
During the oxidation process, the hydroxyl groups (–OH) in sucrose can be oxidized, leading to the formation of carboxylic acids.

4. **Identify the Products**:
The primary product of the oxidation of sucrose with concentrated HNO3 is oxalic acid (C2H2O4). Additionally, nitrogen dioxide (NO2) gas is released, along with water (H2O).

5. **Write the Balanced Reaction**:
The overall reaction can be summarized as:
\[ C_{12}H_{22}O_{11} + HNO_3 \rightarrow C_2H_2O_4 + NO_2 + H_2O \]
This indicates that one mole of sucrose reacts with nitric acid to produce oxalic acid, nitrogen dioxide, and water.

6. **Conclusion**:
Therefore, the product formed when sucrose is heated with concentrated HNO3 is oxalic acid.

### Final Answer:
The product is **oxalic acid (C2H2O4)**.
