Question: The absolute value of the electron gain enthalpy of halogens satisfies:
$\mathrm{I}>\mathrm{Br}>\mathrm{Cl}>\mathrm{F}$
$\mathrm{Cl}>\mathrm{Br}>\mathrm{F}>\mathrm{I}$
$\mathrm{Cl}>\mathrm{F}>\mathrm{Br}>\mathrm{I}$
$\mathrm{F}>\mathrm{Cl}>\mathrm{Br}>\mathrm{I}$
Correct Option: , 3
Solution:
Order of electron gain enthalpy
(Absolute value)
$\mathrm{Cl}>\mathrm{F}>\mathrm{Br}>\mathrm{I}$
