Question

a graph for 4 pi r^2 Ψ^2 (r) V/s r is plotted for H orbital curves contains 3 maxima .if orbital contains angular node then orbital is a) 5d b) 4d c)5p d ) 4p

Answer 1

Given:

A graph for 4 pi r^2 Ψ^2 (r) V/s r is plotted for H orbital curves contains 3 maxima.

To find:

If orbital contains angular node then orbital is a) 5d b) 4d c)5p d ) 4p

Solution:

From given, we have,

The number of angular nodes = 2

⇒ l = 2  

2 indicates d orbital.

Maxima = n - l

3 = n - 2

3 + 2 = n

∴ n = 5

5d orbital.

Therefore, option a) 5d is correct.
