Question

$As{F}_5$ 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. $s,p_x,p_y,p_z,d_{z^2}$
• D. $d_{x^2-y^2},s,p_x,p_y,p_z$.

Answer 1

The correct option is C $s,p_x,p_y,p_z,d_{z^2}$

It is clear from the image that the orbitals are

$s,p_x,p_y,p_z,d_{z^2}$

$threeP$ orbitals are in a plane and $oned$ orbital is along the axis,

So the correct answer is [C].
