The catenation tendency of C, Si, and Ge...

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

A

`167, 180, 348`

B

`180, 167, 348`

C

`348, 167, 180`

D

`398, 180, 167`

Text Solution

Verified by Experts

The correct Answer is:
D
The tendency to catenate is directly related to the strength of element-element bond. The greater the bond enthalpy of element-element bond, the higher is the catenation tendency.
