Which of the following is correct about 3d orbital

Question

Which of the following statements is correct about 3d orbital?

a) The 3d orbitals remain degenerate in presence of magnetic field

b) The electron densities in the xy and us planes are zero in 3d_xz  orbital

c) The electron density in xy plane in 3d_z ² orbital is zero

d) The electron density in xy plane in 3d_xy  orbital is zero

Answer 1

Option B is correct

3d_xz involves xy and yz nodal planes so the densities in xy and yz planes are zero
