Question

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

$C > > Si > Ge \approx Sn$

Explanation

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 $C > > Si > Ge \approx Sn$ .
