Question

Consider the following radial distribution function diagrams. Which of the following has the correct matching of curve and orbital ?

• A. I(3s), II(3p), III(3d)
• B. I(3d), II(3p), III(3s)
• C. I(3s), II(3d), III(3p)
• D. I(3p), II(3d), III(3s)

Answer 1

Answer: (D)

No of radial node = n - ℓ - 1 .

I(3p) ---- n = 3 and ℓ =1. One radial node

II(3d) ---- n = 3 and ℓ =2. No radial node

III(3s) ---- n = 3 and ℓ =0. Two radial nodes.

All the orbitals provided in choices belong to match. I(3p), II(3d), III(3s)
