Consider the following reactions:
\[
X + \text{O}_2 \;\longrightarrow\; \text{Cu}_2\text{O} + \text{SO}_2
\]
\[
\text{Cu}_2\text{O} + 2\,\text{H}_2 \;\longrightarrow\; 2\,\text{Cu} + \text{H}_2\text{O}
\]
If the molecule \(Y\) is formed in the first reaction, the shape of molecule \(Y\) is:
Show Hint
- Linear
- Tetrahedral
- Pyramidal
- Angular
The Correct Option is D
Solution and Explanation
Step 1: Identify Molecule \(Y\) - In the reaction \(\text{X} + \text{O}_2 \rightarrow \text{Cu}_2\text{O} + \text{SO}_2\), the gas produced is \(\text{SO}_2\). - Therefore, \(Y\) is \(\text{SO}_2\).
Step 2: Structure of \(\text{SO}_2\) - \(\text{SO}_2\) has a bent (or V-shaped) structure due to the presence of a lone pair on the sulfur atom and two S–O double bonds. - The bond angle is approximately \(119^\circ\), which makes it an \emph{angular} molecule. Hence, the shape of molecule \(Y\) (\(\text{SO}_2\)) is (angular).
