Arrange the following in order of:
(a) Increasing oxidation no:
`MnCl_(2),MnO_(2),Mn(OH)_(3),KMnO_(4)`
(b) Decreasing oxidation no:
`HXO_(4),HXO_(3),HXO_(2),HXO`
(c ) Increasing oxidation no.: `I_(2),HI,HIO_(4),ICI`

Text Solution

Verified by Experts

`Mn^(+2) Cl_(2) lt Mn^(+3) (OH)_(3) lt Mn^(+4) O_(2) lt KMn^(+7)O_(4)`
`H overset(+7)(X)O_(4) gt H overset(+5)(X) O_(3) gt H overset(+3) (X) O_(2) gt H overset(+1) (X)O`
(c) `H overset(-1) (I) lt I_(2)^(0) lt overset(+1) (ICl) gt H overset(+7)(I) O_(4)`
