All the d-orbitals have the same shape , Double Dumbbell. However , each of the 5 orbitals have different spacial orientations. ... In dx2-y2 orbital , all the four lobes lie on the co-ordinate axes. In dz2 orbital , there are 2 lobes which lie on the z-axis i.e. one lobe on the +ve z-axis and other on the -ve z-axis.
