Given below are two statements labelled as Assertion (A) and Reason (R) Assertion (A): Electron gain enthalpy of oxygen is less than that of Flourine but greater than Nitrogen. Reason (R): Ionisation enthalpies of the elements follow the order Nitrogen > Oxygen > Fluorine Select the most appropriate answer from the options given below: (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 but R is true.

Answer»

Answer is (c) A is true but R is false.

Assertion: Electron gain enthalpy of oxygen is less than that of Flourine but greater than Nitrogen. (correct)

Reason: Ionisation enthalpies of the elements follow the order Nitrogen > Oxygen > Fluorine (incorrect)

Ionisation enthalpies of the elements follow the order Fluorine >Nitrogen > Oxygen
