Question

On addition of small amount of KMnO₄ to conc.H₂SO₄, a green oily compound is obtained which is highly explosive in nature. Identify the compound from the following.

A. Mn₂O₇
B. MnO₂
C. MnSO₄
D. Mn₂O₃

Answer 1

The compound obtained is Mn₂O₇, which is highly explosive. The correct answer is option: A. Mn₂O₇

Step-by-step explanation:

• The compound obtained when a small amount of KMnO₄ is added to conc.H₂SO₄ and is highly explosive in nature is Mn₂O₇ (option A).
• KMnO₄ is an oxidizing agent and reacts with H₂SO₄ to form a deep purple solution of Mn₂O₇, also known as manganese heptoxide.
• It is a highly unstable compound that can explode when subjected to heat, shock, or friction. Therefore, it is considered a dangerous explosive.
• Other options such as MnO₂, MnSO₄, and Mn₂O₃ are not known to be highly explosive compounds.
