Which of the following arrangements represent increaseing oxidation number of the central atom?

A

`CrO_2 ^- , ClO_3 ^- , CrO_4 ^(2-) ,MnO_4 ^-`

B

`ClO_3 ^- , CrO_4 ^(2-) ,MnO_4 ^- , CrO_2 ^- `

C

`CrO_2 ^- , ClO_3 ^- ,MnO_4 ^- , CrO_4 ^(2-)`

D

` CrO_4 ^(2-), MnO_4 ^- ,CrO_2 ^- , ClO_3 ^-`

Text Solution

Verified by Experts

Writing the O.N of Cr CI and Mn on each species in the foiur set of ions we have
(a) `CrO_(2)^(-) ,CIO_(3)^(-),CrO_(4)^(2-), MnO_(4)^(-)`
(b) `CIO_(3)^(-),CrO_(4)^(2-),MnO_(4)^(-),CrO_(2)^(-)`
(c ) `CrO_(2)^(-),CIOO_(3),MnO_(4)^(-),CrO_(4)^(2-)`
(d) `CrO_(4)^(2-), MnO_(4)^(-), CrO_(2)^(-),CIO_(3)^(3)`
only in arrangement (a) the O.N of central atom incrases form left to right therefore option (a) is correct
