Question

bond energies of catenated elements are as follows :C-C, 348kj/mol:Si-Sl, 222kj/mol:Ge-Ge, 167kj/mol: which elements would you expect to show maximum catenation and why?
​

Answer 1

Answer:

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 are 348,180,167 respectively.

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 are 348,180,167 respectively.Ge has lowest bond energy, hence lowest catenation tendency.
