Vedclass · Answer

(B) The tendency towards catenation depends on the strength of the element-element bond. As the atomic size increases down the group from $S$ to $Te$,the bond dissociation energy decreases. Although $O$ is smaller than $S$,the $O-O$ bond energy is lower than the $S-S$ bond energy due to significant inter-electronic repulsions between the lone pairs of the small oxygen atoms. Therefore,$S$ exhibits the highest tendency towards catenation among the group $16$ elements.
