Catenation power order is `GeltSiltC` then `C-C,Si-Si` and `Ge-Ge` bond energies are respectively (in kJ/mole):-

The catenation tendency of C, Si and Ge is in the order Ge lt Si lt C . The bond energies (in kJ mol^(-1) ) of C-C, Si-Si and Ge-Ge bonds, respectively, are

The catenation tendency of C, Si , and Ge is in the order Ge lt Si lt C . The bond energies (in kJ mol^(-1) ) of C-C-, Si-Si , and Ge-Ge bonds, respectively, are

Assertion : Silicons are very inert polymers Reason: Both Si-O "and" Si-C bond energies are very high

The order of catenation of C,Si,Ge,Sn is
