Options
- A(A)-(II), (B)-(III), (C)-(I), (D)-(IV)
- B(A)-(III), (B)-(II), (C)-(IV), (D)-(I)
- C(A)-(III), (B)-(II), (C)-(I), (D)-(IV)
- D(A)-(II), (B)-(III), (C)-(IV), (D)-(I)
Correct answer
C. (A)-(III), (B)-(II), (C)-(I), (D)-(IV)
Step-by-step solution
The d_ xy orbital has four lobes situated between the x and y axes, so (A) matches with (III). The d_ x^2-y^2 orbital has four lobes directed exactly along the x and y axes, so (B) matches with (II). The d_ z^2 orbital consists of two lobes along the z-axis and a doughnut-shaped ring of electron cloud in the xy plane, so (C) matches with (I). The p_x orbital is a single dumb-bell with two lobes directed along the x-axis, so (D) matches with (IV). Therefore, the correct matching is (A)-(III), (B)-(II), (C)-(I), (D)-
