Catenation i.e., linking of similar atoms depends on size and electronic configuration of atoms. The tendency of catenation in Group 14 elements follows the order
A.
$$C > Si > Ge > Sn$$
B.
$$C > > Si > Ge \approx Sn$$
C.
$$Si > C > Sn > Ge$$
D.
$$Ge> Sn > Si > C$$
Answer :
$$C > > Si > Ge \approx Sn$$
Solution :
As we go down the group, the atomic size increases and electronegativity decreases and thereby, tendency to show catenation decreases. Hence, the order of catenation is $$C > > Si > Ge \approx Sn.$$
