Question

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

• A. 167, 180 and 348
• B. 180, 167 and 348
• C. 348, 167 and 180
• D. 348, 180 and 167

Answer 1

The correct option is D 348, 180 and 167

Higher the bond energy, stronger is the bond. So, more is the catenation tendency.
