Vedclass · Answer

(D) The bond dissociation energy order for halogens is $Cl_2 > Br_2 > F_2 > I_2$ because of the small size of the $F$ atom,which leads to strong inter-electronic repulsion between the non-bonding electrons. Thus,option $(a)$ is incorrect.For electron gain enthalpy,the order is $Cl > F > Br > I$. Due to the small size of $F$,the incoming electron experiences more repulsion,making its electron gain enthalpy less negative than that of $Cl$. Thus,option $(c)$ is also incorrect.Therefore,both $(a)$ and $(c)$ represent incorrect trends.
