Which among the following pair of elements show highest oxidation state $+7$ in their different compounds? (Atomic no. $\mathrm{Cr}=24, \mathrm{~V}=23, \mathrm{Mn}=25, \mathrm{Cl}=17, \mathrm{~S}=16$ )
$\mathrm{Mn}, \mathrm{Cl}$
$\mathrm{Cr}, \mathrm{Mn}$
$\mathrm{V}, \mathrm{Mn}$
$\mathrm{S}, \mathrm{Cl}$
Solution
Highest oxidation state of $\mathrm{Cr}=+6, \mathrm{Mn}=+7, \mathrm{Cl}=+7, \mathrm{~S}=+6, \mathrm{~V}=+5$
