Question

The five d-orbitals are designated as `d_"xy", d_"yz", d_"xz",d_(x^2-y^2)` and `d_z^2` . Choose the correct statement
A. The shapes of the first three orbitals are similar but that of the fourth and fifth orbitals are different
B. The shapes of all five d-orbitals are similar
C. The shapes of the first four orbitals are similar but that of the fifth orbital is different
D. The shapes of all five d-orbitals are different

Answer 1

Correct Answer - C
First four orbitals contain four lobes, while fifth orbital consists of only two lobes. The lobes of `d_"xy"` orbital lie between x and y axis. Similar is the case for `d_"yz"` and `d_"zx"` .Four lobes of `d_(x^2-y^2)` orbital are lying along x and y axis while two lobes of `d_z^2` orbital are lying along z-axis
