Question: The correct order of catenation is :
$\mathrm{C}>\mathrm{Si}>\mathrm{Ge} \approx \mathrm{Sn}$
$\mathrm{C}>\mathrm{Sn}>\mathrm{Si} \approx \mathrm{Ge}$
$\mathrm{Ge}>\mathrm{Sn}>\mathrm{Si}>\mathrm{C}$
$\mathrm{Si}>\mathrm{Sn}>\mathrm{C}>\mathrm{Ge}$
Correct Option: 1
Solution:
As we move down the group, bond strength decreases, thereby decreasing the catenation tendency.
Hence the order is as expected $\mathrm{C}>\mathrm{Si}>\mathrm{Ge} \approx \mathrm{Sn}$
