NEET Chemistry Orbitals Assertion Reason Question
Type: Assertion Reason-assertion-Medium-Class 11
Assertion (A): Electrons in s orbitals shield outer electrons more effectively than those in p orbitals. | Reason (R): Electrons in s orbitals spend more time closer to the nucleus due to their spherical shape compared to p orbitals.
A
Both A and R are true, and R is the correct explanation of A.
B
Both A and R are true, but R is not the correct explanation of A.
C
A is true, but R is false.
D
A is false.
Correct Answer
Option A
Detailed Explanation
The NCERT context states that s orbitals, due to their spherical shape, allow electrons to spend more time closer to the nucleus, effectively shielding outer electrons. This directly supports both the assertion and reason.
