NEET Chemistry Ionic Bond Assertion Reason Question
Assertion (A): Lattice enthalpy is a key factor in determining the stability of ionic compounds.
Reason (R): Ionic bonds form more easily between elements with high ionization enthalpy and low electron gain enthalpy.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true, but R is false.
A is false.
Correct Answer
Detailed Explanation
Lattice enthalpy is indeed crucial for the stability of ionic compounds as it provides a measure of the energy released when ions form a lattice. However, ionic bonds form more easily when elements have low ionization enthalpy and high negative electron gain enthalpy, contrary to what is stated in the Reason.
