Question

Manganese exhibits maximum oxidation state in:

• A. $K_{2}Mn{O}_4$
• B. $KMn{O}_4$
• C. $Mn{O}_2$
• D. $M{n}_3{O}_4$

Answer 1

The correct option is B $KMn{O}_4$

Manganese exhibits maximum oxidation state in:

$K_{2}Mn{O}_4$ ---- +6

$KMn{O}_4$-------- +7 $(+1+x+4(-2)=0);\Rightarrow x=+7$

$Mn{O}_2$--------- +4

$M{n}_3{O}_4$------ +2 and +3

Manganese exhibits maximum oxidation state in $KMn{O}_4$

Hence option B is correct.
