NEET Chemistry Ionic Bond Assertion Reason Question

Type: Assertion Reason-assertion-Hard-Class 11

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.

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.
