All of these

Vedclass · Answer

(D) $1$. The bond dissociation energy of $F-F$ is lower than $Cl-Cl$ due to high inter-electronic repulsion between the lone pairs of the small $F$ atoms. Thus,$F-F $2$. Thermal stability of hydrogen halides decreases down the group as the bond length increases and bond dissociation energy decreases. Thus,$HF > HCl > HBr > HI$ is correct.$3$. Reducing power of hydrogen halides increases down the group as the bond dissociation energy decreases,making it easier to release $H$ atoms. Thus,$HI > HBr > HCl > HF$ is correct.Since all statements are correct,the correct option is $D$.
