Identify the correct statements from the following:
Show Hint
- PCl\(_5\) has a trigonal bipyramidal structure, where axial bonds are longer than equatorial bonds.
- Zinc and dilute HNO\(_3\) produce multiple nitrogen oxides, not just NO\(_2\).
- Rhombic sulfur is the most stable allotrope at room temperature.
- SO\(_2\) to SO\(_3\) oxidation in the Contact Process is catalyzed by V\(_2\)O\(_5\) and is an exothermic reaction.

The Correct Option is D
Solution and Explanation
The given question asks us to identify which statements are correct from the provided options. We will analyze each statement step-by-step.
-
Statement 1: In PCl5, equatorial bonds are longer than axial bonds.
- PCl5 has a trigonal bipyramidal structure.
- This structure includes 3 equatorial bonds and 2 axial bonds.
- Typically, axial bonds are longer than equatorial bonds due to greater repulsion from more axial atoms.
- Therefore, this statement is incorrect.
-
Statement 2: Zinc reacts with dilute nitric acid to give NO2.
- Generally, when zinc reacts with dilute nitric acid, it typically forms zinc nitrate, water, and nitrogen oxides such as NO or N2O.
- NO2 is generally associated with more concentrated nitric acid reactions.
- Therefore, this statement is incorrect.
-
Statement 3: Rhombic sulphur is yellow in colour.
- Rhombic sulphur, also known as alpha-sulphur, is indeed yellow in color.
- Therefore, this statement is correct, but it is not mentioned as the correct answer choice in the given solution.
-
Statement 4: The reaction \(2SO_2(g) + O_2(g) \xrightarrow{V_2O_5} 2SO_3(g)\) is exothermic.
- This is the process of forming sulfur trioxide from sulfur dioxide and oxygen in the presence of a vanadium(V) oxide catalyst.
- The reaction releases heat, making it exothermic, which matches the reported correct answer.
- Therefore, this statement is correct.
Thus, the correct statement is: The reaction \(2SO_2(g) + O_2(g) \xrightarrow{V_2O_5} 2SO_3(g)\) is exothermic.
