Vedclass · Answer

(C) Catenation is the ability of an element to form bonds with other atoms of the same element to form long chains or rings. In group $14$,the tendency to show catenation decreases down the group due to the decrease in bond dissociation enthalpy of the $M-M$ bond as the atomic size increases. The order of catenation is $C \gg Si > Ge = Sn$. $Pb$ does not show catenation due to its large atomic size and weak $Pb-Pb$ bond.
