AsF(5) molecule is trigonal bipyramidal....

`AsF_(5)` molecule is trigonal bipyramidal. The orbitals of As atom involved in hybridisation are

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`

Text Solution

Verified by Experts

The correct Answer is:
C
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)`
