Which one of the following arrangements does not give the correct picture of the trends indicated against it ?

Options

A. `F_(2)gt Cl_(2) gt Br_(2) gt I_(2)` : Electronegativity
B. `F_(2) gt Cl_(2) gt Br_(2) gt I_(2)` : Oxizied power
C. `F_(2) gt Cl_(2) gt Br_(2) gt I_(2)` : Electron gain enthalpy
D. `F_(2) gt Cl_(2) gt Br_(2) gt I_(2)` : Bond dissociation energy

Answer

3, 4

Explanation

Correct order of electron gain enthalpy
`underset((-349" kJ"//"mol"))(Cl) gt underset((-333))(F) gt underset((-325))(Br) gt underset((-296))(I)`
Correct order of bond dissociation enthalpy of
`underset((242.6" kJ"//"mol"))(Cl_(2)) gt underset((192.8))(Br_(2)) gt underset((158.8))(F_(2)) gt underset((151.1))(I_(2))`
