Dear deeksha,

(i) The three orbitals dxy, dyz, and dzx are similar and each consists of four lobes of high electron density lying in xy, yz and zx planes respectively. These lobes lie in between the principal axes. For e.g., in case of dxy orbital, the four lobes lie in xy plane in between the x and y-axes.

(ii) The dx2- y2 orbital has also four lobes of high electron density along the principal axes x and y. It may be noted that this orbital is exactly like dxy orbital except that it is rotated through 45o around the z-axis.

(iii) The dz2 orbital consists of two lobes along the z-axis with ring of high electron density in the xy plane.
