The tendency of catenation in group-14 elements follows the order :
Options
- AC >> Si > Ge > Sn
- BC >> Si > Ge Sn
- CSi > C > Sn > Ge
- DGe Sn > Si > C
Correct answer
B. C >> Si > Ge Sn
Step-by-step solution
In group 14 , down the group, the size increases and electronegativity decreases, and thereby, tendency to show catenation decreases. The order of catenation is : C >> Si > Ge Sn . Lead does not show catenation. Hence, the correct option is (2).
