NEET Chemistry (general) MCQ Question
Type: MCQ-diagram based-Medium-Class 11
A diagram shows plots of wave functions as a function of distance from the nucleus for 1s and 2s orbitals. Which of the following statements correctly describes the difference between these two orbitals?
A
The 1s orbital has a node at a distance r from the nucleus.
B
The 2s orbital has a higher probability density at the nucleus compared to the 1s orbital.
C
The 2s orbital has one node, whereas the 1s orbital has none.
D
Both 1s and 2s orbitals have the same radial distribution of electrons.
Correct Answer
Option C
Detailed Explanation
According to the NCERT, the 2s orbital has one node, while the 1s orbital does not have any nodes, as shown in the plots of their wave functions.
