When `KMnO_(4)` acts as an oxidising agnet and ultimetely from `MnO_(4)^(2-), MnO_(2), Mn_(2)O_(3)`, and `Mn^(2+)`, then the number of electrons transferred in each case, respectively, are

A

4,3,1,5

B

1,5,3,7

C

1,3,4,5

D

3,5,7,1

Text Solution

Verified by Experts

The correct Answer is:
C
`overset(+7)(KMnO_(4))overset(+1e^(-))(rarr)(overset(+6)(MnO_(4)))^(2-)`
`overset(+7)(KMnO_(4))overset(+3e^(-))(rarr)overset(+4)(MnO_(2))`
`overset(+7)(KMnO_(4))overset(+4e^(-))(rarr)(1)/(2)overset(+3)(Mn_(2)O_(3))`
`(2x-6=0orx=3)`
`overset(+7)(KMnO_(4))overset(+5e^(-))(rarr)overset(+2)(Mn)`.
