The correct order of catenation is :
Question:

The correct order of catenation is :

1. $\mathrm{C}>\mathrm{Si}>\mathrm{Ge} \approx \mathrm{Sn}$

2. $\mathrm{C}>\mathrm{Sn}>\mathrm{Si} \approx \mathrm{Ge}$

3. $\mathrm{Ge}>\mathrm{Sn}>\mathrm{Si}>\mathrm{C}$

4. $\mathrm{Si}>\mathrm{Sn}>\mathrm{C}>\mathrm{Ge}$

Correct Option: 1

Solution:

As we move down the group, bond strength decreases, thereby decreasing the catenation tendency.

Hence the order is as expected $\mathrm{C}>\mathrm{Si}>\mathrm{Ge} \approx \mathrm{Sn}$
