Question

Orbital having 3 angular nodes and 3 total nodes is:

A

5p

B

3d

C

4f

D

6d

Step-by-Step Solution

The number of angular nodes in an orbital is determined by the azimuthal quantum number (ll), and the total number of nodes is given by (n−1)(n - 1), where nn is the principal quantum number.

  1. Angular Nodes: Given as 3. Since angular nodes = ll, we have l=3l = 3. An orbital with l=3l = 3 corresponds to an f-orbital.
  2. Total Nodes: Given as 3. Since total nodes = n−1n - 1, we have n−1=3n - 1 = 3, which implies n=4n = 4.

Combining these, the orbital with n=4n = 4 and l=3l = 3 is the 4f orbital.
