NEET Chemistry (general) Assertion Reason Question
Type: Assertion Reason-assertion-Hard-Class 11
Assertion (A): An electron in the 4p orbital of bromine experiences a lower effective nuclear charge than an electron in the 3p orbital. | Reason (R): Electrons in higher energy orbitals experience greater shielding effect due to inner electrons.
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
Electrons in higher orbitals like 4p experience more shielding and thus a lower effective nuclear charge compared to those in 3p. The reason correctly explains this effect.
