1. `Cl_(2)` 2. `MnO_(4)^(-)` 3. `NO_(2)` 4. `ClO_(4)^(-)`
The correct statement is/ are

A

`Cl_(2)`

B

`MnO_(4)^(-)`

C

`NO_(2)`

D

`ClO_(4)^(-)`

Text Solution

Verified by Experts

The correct Answer is:
C
`overset((0))(Cl_(2))-2NaOH to Na overset((-1))(Cl)+NaO overwset((+1))(Cl)+H_(2)O`
`overset((+4))(NO_(2))+2NaOH to Na overset((+3))(NO_(2))+Na overset((+5))(NO_(3))+H_(2)O`
