On heating `NaX` with `H_(2)SO_(4)` and `MnO_(2)` the halogen that cannot be prepared is

A

`l_(2)`

B

`F_(2)`

C

`Cl_(2)`

D

`Br_(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
`MnO_(2)` can oxidise `NaCl, NaBr` and `NaI` and not `NaF`. Hence `F_(2)` cannot be prepared by this method.
