The orbitals are called degenerate when

A

they have the same wave functions

B

they have the same wave functions but different energies

C

they have different wave functions but same energy

D

they have the same energy

Text Solution

Verified by Experts

The correct Answer is:
D
(d) The orbitals having the same energy energy but different in orientation, are called degenerate orbitals . E.g. 3d-orbital, l=2, m=-2,-1,0,+1,+2, i.e. there are five different orientations represented by `d_(xy),d_(yz),d_(zx),d_(x^(2)-y^(2))` and `d_(z^(2))`.
