The orbitals are called degenerate when

Options

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

Answer

D

Explanation

(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))`.
