Which of the following represents the correct order of increasing electron gain enthalpy with negative sign for the elements O, S, F and Cl?

A

`F lt S lt O lt Cl`

B

`S lt O lt Cl lt F`

C

`Cl lt F lt O lt S`

D

`O lt S lt F lt Cl`

Text Solution

Verified by Experts

The correct Answer is:
D
Electron gain enthalpy of Group 17 element (with positive sign) is greater than `DH_(eg)` of Group 16 elements. Hence the correct answer is
`O lt S lt F lt Cl`.
