STANDARD Chemistry Quantum Numbers MCQ Question
Type: MCQ-conceptual-Medium-Class 11
The number of radial nodes and angular nodes ion for d-orbital can be represented as
A
(n−2) radial nodes +1 angular node = (n−1) total nodes
B
(n−1) radial nodes +1 angular node = (n−1) total nodes
C
(n−3) radial nodes +2 angular nodes = (n−l−1) total nodes
D
(n−3) radial nodes +2 angular nodes = (n−1) total nodes
Correct Answer
Option D
Detailed Explanation
Total number of nodes = n−1. For d-orbital, radial nodes = n−l−1 = n−3 and there are 2 angular nodes.
