Vedclass · Answer

(C) The sign of the wave function $\psi$ for an orbital determines the phase of the electron wave. For a $p$-orbital,the two lobes must have opposite signs (one positive,one negative) due to the presence of a nodal plane. For a $d$-orbital,the lobes are arranged such that adjacent lobes have opposite signs. In the $d_{x^2-y^2}$ orbital,the lobes lie along the $x$ and $y$ axes. The standard representation of a $d_{x^2-y^2}$ orbital shows the lobes along the $x$-axis having one sign (e.g.,positive) and the lobes along the $y$-axis having the opposite sign (e.g.,negative). Option $C$ shows all four lobes of the $d_{x^2-y^2}$ orbital with a positive sign,which is incorrect as it violates the symmetry requirements of the wave function for this orbital.

Which of the following notations of an orbital is incorrect considering the sign of the wave function?
