Which of following pairs of d-orbitals will have electron density along the axis?

Options

A. `dz^(2), dx^(2)-y^(2)`
B. `dxy, dx^(2)-y^(2)`
C. `dz^(2), dxz`
D. `dxz, dyz`

Answer

A

Explanation

`dz^(2) and dx^(2)-y^(2)` have electron density concentrated on the axis, others have electron density between the axis.
