(D) The correct order of electron gain enthalpy is $Cl > F > Br > I$. Due to the small size of the $F$ atom,there is strong inter-electronic repulsion

Vedclass · Accepted Answer

Bond dissociation energy: $F_2 > Cl_2 > Br_2$

Vedclass · Answer

(D) The correct order of electron gain enthalpy is $Cl > F > Br > I$. Due to the small size of the $F$ atom,there is strong inter-electronic repulsion,making the addition of an electron less favorable compared to $Cl$. Thus,$F Also,the bond dissociation energy order is $Cl_2 > Br_2 > F_2 > I_2$. The $F-F$ bond is weaker than the $Cl-Cl$ bond due to high inter-electronic repulsion between the lone pairs of the small $F$ atoms. Therefore,both options $B$ and $D$ are inconsistent with the properties indicated. However,in standard multiple-choice questions of this type,$D$ is often the primary focus due to the anomalous weakness of the $F-F$ bond.

Which of the following is $NOT$ consistent with the property indicated against it?
