Vedclass · Answer

(C) $1$. Bond dissociation energy: Due to the small size of the $F$ atom,the lone pairs on the $F$ atoms in $F_2$ experience strong inter-electronic repulsion,making the $F-F$ bond weaker than the $Cl-Cl$ bond. Thus,the order is $Cl-Cl > F-F$. Statement $A$ is incorrect.$2$. Thermal stability: Thermal stability decreases down the group as the bond length increases and bond dissociation energy decreases. The correct order is $HF > HCl > HBr > HI$. Statement $B$ is incorrect.$3$. Reducing power: Reducing power increases as the bond dissociation energy decreases down the group. The correct order is $HI > HBr > HCl > HF$. Statement $C$ is correct.
