Question

Oxidation number of $Mn$ in $Mn{O}_{3}Cl$ is +6. If true enter 1, else enter 0.

• A. 0

Answer 1

The correct option is A 0
Let $x$ be the oxidation number of $Mn$ in $Mn{O}_{3}Cl$.
Since the overall charge on the complex is $0$, the sum of oxidation states of all elements in it should be equal to $0$.
Therefore, $x+3(-2)+(-1)=0$
or, $x=7$.
