Q. The $AsF_{5}$ molecule is trigonal bipyramidal.The hybrid orbitals used by the As atoms for bonding are
A) $d_{x^{2} - y^{2}},{\ d}_{z^{2}},\ s,\ P_{x},P_{y}\$
B) $d_{xy},s,P_{x},P_{z}$
C) $s,\ P_{x},\ P_{y},\ P_{z},d_{z^{2}}$
D) $d_{x^{2} - y^{2}},\ s,\ P_{x},P_{y}$
Explanation
(c)
Since, the geometry of $AsF_{5}$ molecule is trigonal bipyramidal, it is $sp^{3}d$ hybridised. Thus, s,$\ p_{x},\ \ p_{y},\ \ p_{z}$ and $d_{z^{2}}$ orbitals are utilised by As atom from bonding.
