`MnO_2 + HCl overset(Delta)to A_((s))`
`A_((g)) + F_(2"(excess)") overset(573K)to B_((s))`
`B_((l)) + U_((s)) to C_((g)) + D_((g))`
The gases A,B,C and D are respectively

Options

A. `Cl_2,ClF, UF_6, ClF_3`
B. `Cl_2, ClF_3, UF_6,ClF`
C. `O_2, OF_2, U_2O_3, O_2F_2`
D. `O_2, O_2F_2, U_2O_3, OF_2`

Answer

B

Explanation

` MnO_2 + 4Cl overset(Delta)to underset((A))(Cl_2) + MnCl_2 + 2H_2O`
`Cl_2 + F_(2"(excess)") to ClF_3 (B)`
`3ClF_3 + U_((5)) to underset((C))(UF_6) + underset((D))(3ClF)`
`A = Cl_2`
`B=ClF_3`
`C=UF_6`
`D=ClF`
