Question

In the following reaction: \[ \text{C} + \text{Conc.} \, \text{H}_2\text{SO}_4 \xrightarrow{\Delta} \text{X} + \text{Y} + \text{H}_2\text{O} \] X and Y in the above reaction are:

• A. \(\text{CO}, \, \text{SO}_3\)
• B. \(\text{CO}_2, \, \text{SO}_2\)
• C. \(\text{CO}, \, \text{SO}_2\)
• D. \(\text{C}_3\text{O}_2, \, \text{SO}_2\)

Hint:

In reactions involving carbon and sulfuric acid, the products usually include \(\text{CO}_2\) and \(\text{SO}_2\) under appropriate conditions.

Answer 1

The Correct Option is B

When carbon (\(\text{C}\)) reacts with concentrated sulfuric acid (\(\text{H}_2\text{SO}_4\)) and is heated, the reaction produces carbon dioxide (\(\text{CO}_2\)) and sulfur dioxide (\(\text{SO}_2\)) gases. The sulfuric acid provides the sulfur that reacts with carbon to form sulfur dioxide, while the carbon dioxide is a product of the oxidation of carbon.
