NEET Chemistry (general) Assertion Reason Question
Type: Assertion Reason-assertion-Hard-Class 11
Assertion (A): The formation of NaCl involves the transfer of electrons from sodium to chlorine.
Reason (R): NaCl formation is primarily driven by the enthalpy of lattice formation, which is greater than the sum of ionization energy and electron affinity.
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 explains that NaCl formation involves electron transfer from Na to Cl and is driven by the large negative enthalpy of lattice formation, which compensates for the ionization energy and electron affinity.
