(A) Electron density in the $xy$-plane in $3d_{x^2-y^2}$ orbital is zero.
(B) Electron density in the $xy$-plane in $3d_{z^2}$ orbital is zero.
(C) $2s$-orbital has one nodal surface.
(D) For $2p_x$-orbital $yz$ is the nodal plane.

Which are the correct statements?

• A. (C) and (D)
• B. (B) and (C)
• C. Only (B)
• D. (A), (B), (C) and (D)

Answer 1

The correct option is A (C) and (D)

(C) and (D) are the correct statements.
(A) Electron density in the xy-plane in $3d_{x^2-y^2}$ orbital is non zero.
(B) Electron density in the xy-plane in $3d_{z^2}$ orbital is non zero.
(C) 2s-orbital has one nodal surface.
(D) For 2px-orbital yz is the nodal plane.
