Question

In an octahedral structure, the pair of $d$ orbitals involved in $d^2sp^3$ -hybridisation is

• A. $d_{x^2 -y^2},d_{Z^2}$
• B. $d_{xz},d_{x^2-y^2}$
• C. $d_{z^2} ,d_{xz}$
• D. $ d_{xy} ,d_{yz}$

Answer 1

Answer: (A)

In the formation of $d^2sp^3$ hybrid orbitals, two $(n - 1) d$-orbitals of eg set, i.e. $(n-1) d_{z^2}$ and $(n-1) d_{x^2-y^2}$ orbitals, one $ns$ and three $np$ ($np_x, np_y$ and $ np_z $ .) orbitals combine together.
