Observe the given figure showing the boundary surface diagrams of four different atomic orbitals labeled P, Q, R, and S. Match the orbital shapes in List I with their corresponding designations and azimuthal quantum numbers in List II. List I List II A Shape P 1 p_x orbital, l = 1 B Shape Q 2 d_ z^2 orbital, l = 2 C Shape R 3 s orbital, l = 0 D Shape S 4 d_ xz orbital, l = 2 Choose the correct answer from the options
Options
- A(A)-(3), (B)-(1), (C)-(4), (D)-(2)
- B(A)-(3), (B)-(1), (C)-(2), (D)-(4)
- C(A)-(2), (B)-(4), (C)-(1), (D)-(3)
- D(A)-(1), (B)-(3), (C)-(4), (D)-(2)
Correct answer
A. (A)-(3), (B)-(1), (C)-(4), (D)-(2)
Step-by-step solution
Shape P is spherically symmetric, which corresponds to an s orbital. For an s orbital, the azimuthal quantum number is l = 0 . Thus, A matches with 3. Shape Q has two lobes oriented along the x-axis, which corresponds to a p_x orbital. For a p orbital, l = 1 . Thus, B matches with 1. Shape R has four lobes lying in the xz plane between the x and z axes, which corresponds to a d_ xz orbital. For a d orbital, l = 2 . Thus, C matches with 4. Shape S has two lobes along the z-axis and a donut-shaped ring in the xy plan
