- D(A)-(I), (B)-(III), (C)-(IV), (D)-(II)
Correct answer
B. (A)-(I), (B)-(III), (C)-(II), (D)-(IV)
Step-by-step solution
The number of maxima (peaks) in the radial probability distribution curve ( 4 r^2 ^2 versus r ) for an orbital is equal to the number of radial nodes plus one. Number of peaks = (n - l - 1) + 1 = n - l . Calculating the number of peaks for each given orbital: (A) 2p : n = 2 , l = 1 . Number of peaks = 2 - 1 = 1 . Matches with (I). (B) 3s : n = 3 , l = 0 . Number of peaks = 3 - 0 = 3 . Matches with (III). (C) 4d : n = 4 , l = 2 . Number of peaks = 4 - 2 = 2 . Matches with (II). (D) 4s : n = 4 , l = 0 . Number of pea
