When a brown compound of Mn (A) is teated with HCl, it gives a gas (B). The gas (B) taken in excess reacts with `NH_(3)` to give an explosive compound (C). The compounds A, B and C are

A

`A = MnO_2 , B = Cl_2 , C = NCl_3`

B

`A = MnO, B = Cl_2 , C = NH_3 Cl`

C

` A = Mn_3O_4, B = Cl_2, C = NCl_3`

D

`A = MnO_3, B = Cl_2 , C = NCl_2`

Text Solution

Verified by Experts

The correct Answer is:
A
`underset((A)) (MnO_2) + 4HCl to underset((B)) (Cl_2) + MnCl_2 + 2H_2O`
`underset(("excess"))(3Cl_2) + NH_3 to underset((c)) (NCl_3) + 3HCl `
