Answer: 3dxy and [tex]3dz^2 [/tex] are degenerate.

4dxy, 4dyz and 4dz^2 are degenerate.

Explanation:

Degenerate orbitals are those orbitals which have same value of energy.

Principle Quantum Numbers : It describes the size of the orbital and the energy level. It is represented by n. Where, n = 1,2,3,4....

Azimuthal Quantum Number : It describes the shape of the orbital. It is represented as 'l'. The value of l ranges from 0 to (n-1). For l = 0,1,2,3... the orbitals are s, p, d, f...

Energy of orbitals is given by the expression:

E=\frac{-Z^2hR}{n^2}

As E depends only on quantum number n, thus orbitals which have same value of n will have same energy.

3dxy and 3dz^2 with n=3, will have same energy and and are degenerate

4dxy, 4dyz and 4dz^2 with n=4, will have same energy and and are degenerate
