(a) $\mathrm{C}>\mathrm{Sn}>\mathrm{Si} \approx \mathrm{Ge}$
(b) $\mathrm{Si}>\mathrm{Sn}>\mathrm{C}>\mathrm{Ge}$
(c) $\mathrm{C}>\mathrm{Si}>\mathrm{Ge} \approx \mathrm{Sn}$
(d) $\mathrm{Ge}>\mathrm{Sn}>\mathrm{Si}>\mathrm{C}$
Show Answer
Answer:
Correct Answer: 3. (c)
Solution:
- Catenation property is an unique property of group $14$ elements. Down the group $14$, catenation power decreases as:
$ \mathrm{C}>\mathrm{Si}>\mathrm{Ge} \approx \mathrm{Sn} $
Pb does not show catenation.
