In the presence of strong electrical field, the following set of orbitals are not degenerate

Options

A. `3d_(xy)` and `3d_(z^(2))`
B. `3d_(xy)` and `3d_(yz)`
C. `3d_(xy), 3d_(yz)` and `3d_(zx)`
D. `3d_(x^(2) - y^(2))` and `3d_(z^(2))`

Answer

A

Explanation

In d orbital the splitting is
a) `dxy, dyz,dzx`- degenerate orbitals
b) `d_(x^(2)- y^(2)), d_(z^(2))` degenerate orbitals
