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 the five d-orbitals are different.

Answer 1

Answer: (C)

First four orbitals contain four lobes, while fifth orbital consists of only tow lobes. The lobes of d${}_{xy}$ orbital lie between x and y axes. Si.nil .. r is the case for $d_{yz}and{d}_{zx}$Four lobes of $d_{x^1-y^2}$ orbital are lying along x and y axes while two lobes of d${}_{z^2}$orbital arc lying along z-axis
