Best answer

Answer: 2. \(d_{z^2}, d_{x^2-y^2}\)

Key idea: \(d_{z^2}\) and \(d_{x^2-y^2}\) have lobes along the axes; \(d_{xy}, d_{yz}, d_{xz}\) have lobes between the axes.

So the pair with density along the axes is \(d_{z^2}, d_{x^2-y^2}\). These are the \(e_g\) orbitals, which point at ligands in an octahedral complex.
