Thermal decomposition of a Mn compound (...

Thermal decomposition of a Mn compound (X) at 513 K results in compound Y, `MnO_(2)` and a gaseous product. `MnO_(2)` reacts with NaCl and concentrated `H_(2)SO_(4)` to give a pungent gas Z. X, Y and Z respectively, are :

A

HCl, HBr, HI

B

`HCl, Br_(2),I_(2)`

C

`Cl_(2), Br_(2),I_(2)`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
HBr and HI are strong reducing agents and are oxidized by `H_(2)SO_(4) " to " Br_(2) " and" I_(2)`, respectively.
