1.The catenation tendency of C, Si and Ge is in the order Ge<Si<CGe < Si < CGe<Si<C. The bond energies (in kJ mol−1kJ\,mol^{-1}kJmol−1) of C−CC-CC−C, Si−SiSi-SiSi−Si and Ge−GeGe-GeGe−Ge bonds, respectively area.167, 180, 348b.180, 167, 348c.348, 167, 180d.348, 180, 167Login to continueOnly logged in users canattempt or see the solution.
