NEET Chemistry Ionic Bond Assertion Reason Question
Assertion (A): Ionic bonds are formed more easily between elements with low ionization enthalpies and high negative electron gain enthalpies. | Reason (R): Electron gain enthalpy is always exothermic.
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
The assertion is true as ionic bonds are favored by low ionization enthalpies and high negative electron gain enthalpies. However, the reason is false because electron gain enthalpy can be exothermic or endothermic.
