Match the List-I with List-II List-I Orbital List-II Radial nodes and nodal plane A. 2s I. 1 Radial node + two nodal planes B. 3s II. 1 Radial node + one nodal plane C. 3p III. 2 Radial nodes + No nodal plane D. 4d IV. 1 Radial node + No nodal plane Choose the correct answer from the options given below:

Options

  1. AA-IV, B-I, C-III, D-II
  2. BA-IV, B-II, C-III, D-I
  3. CA-III, B-I, C-IV, D-II
  4. DA-IV, B-III, C-II, D-I

Correct answer

D. A-IV, B-III, C-II, D-I

Step-by-step solution

The number of radial nodes is given by the formula n - l - 1 . The number of nodal planes (angular nodes) is given by l . For 2s orbital: n = 2 , l = 0 . Radial nodes = 2 - 0 - 1 = 1 . Nodal planes = 0 . This matches A with IV. For 3s orbital: n = 3 , l = 0 . Radial nodes = 3 - 0 - 1 = 2 . Nodal planes = 0 . This matches B with III. For 3p orbital: n = 3 , l = 1 . Radial nodes = 3 - 1 - 1 = 1 . Nodal planes = 1 . This matches C with II. For 4d orbital: n = 4 , l = 2 . Radial nodes = 4 - 2 - 1 = 1 . Nodal planes = 2
