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.
