Show Answer

Answer:

Correct Answer: B

Solution:

$ XeF_4+SbF_5\xrightarrow{{}}{{[XeF_3]}^{+}}{{[SbF_6]}^{-}}\xrightarrow{{}} $ $ \underset{\begin{smallmatrix} sp^{3}d \\ bentT-shape \end{smallmatrix}}{\mathop{{{[XeF_3]}^{+}}}}+\underset{\begin{smallmatrix} sp^{3}d \\ octahedral \end{smallmatrix}}{\mathop{{{[SbF_6]}^{-}}}} $
