In the reaction of oxalate with permanganate in acidic medium, the number of electrons involved in producing one molecule of `CO_(2)` is

A

5

B

1

C

2

D

10

Text Solution

Verified by Experts

The correct Answer is:
B
`2MnO_(4)^(-)+5C_(2)O_(4)^(2-)rarr10CO_(2)+2Mn^(2+)`
Total `10e^(-)` transfer for 10 molecules of `CO_(2)`
Hence for 1 molecule of `CO_(2)`, only one `e^(-)` is transferred.
