Question

On addition of small amount of $KMn{O}_4$ to concentrated $H_{2}S{O}_4$, a green oily compound is obtained which is highly explosive in nature. Identify the compound from the following.

• A. $M{n}_2{O}_7$
  
• B. $Mn{O}_2$
  
• C. $MnS{O}_4$
  
• D. $M{n}_2{O}_3$
  

Answer 1

The correct option is A $M{n}_2{O}_7$


$2KMn{O}_4+2H_{2}S{O}_4\left(conc\right)⟶M{n}_2{O}_7+2KHS{O}_4+H_{2}O$
