Question

Consider a hypothetical atom where $p_x,p_y,p_z,d_{xy},d_{xz},d_{yz}andd{x}^2-y^2$ orbital are present for principal quantum number n= 3.
Find the number of other orbitals whose lobes are fully present in the nodal plane of $p_x$ orbital:

• A. 2
• B. 3
• C. 4
• D. 5

Answer 1

The correct option is B 3

clearly shown in figure nodal plane of $p_x$ lies in zy plane

and lobes of $3d_{yz}$ and $3d{x^2-y^2} lies totally in zy plane. So, lobes of a total of 3 orbitals lie in zy plane.

Hence, the correct option is $B$
