The `AsF_5` molecule is trigonal bipyramidal. The orbitals used by `As` for hybridisation are

Options

A. `d_(x^2-y^2), d_(z^2),s,p_x,P_y`
B. `d_(xy), s, p_x, p_y,p_z`
C. `s,p_x,p_y,p_z,p_(xy)`
D. `d_(x^2-y^2), s, p_x,p_y, p_z`

Answer

C

Explanation

As =`1s^2, 2s^2 , 2p^6, ubrace(3s^1 3p_x^1 3p_y^1 3p_z^1 3d^1)_(sp^3d "hybridisation")`
Due to this hybridisation, geometry of the `AsF_5` molecule is trigonal bipyramidal and the hybrid orbitals used by As-atom as s,`p_x,p_y,p_z and d_(xy)`
