Vedclass · Answer

(A) The tendency for catenation is directly proportional to the bond dissociation energy of the element-element bond. As we move down the group from $C$ to $Ge$,the atomic size increases,which leads to a decrease in the overlap of orbitals and consequently a decrease in bond strength. The bond dissociation energies for $C-C$,$Si-Si$,and $Ge-Ge$ are approximately $348 \ kJ \ mol^{-1}$,$180 \ kJ \ mol^{-1}$,and $167 \ kJ \ mol^{-1}$ respectively. Therefore,the correct order of bond energies matches the order of catenation tendency.

The catenation tendency of $C$,$Si$ and $Ge$ is in the order $Ge < Si < C$. The bond energies (in $kJ \ mol^{-1}$) of $C-C$,$Si-Si$ and $Ge-Ge$ bonds,respectively,are:
