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:

पर्याय

• C > Si > Ge > Sn

• C >> Si > Ge ≈ Sn

• Si > C > Sn > Ge

• Ge > Sn > Si > C

Answer 1

C >> Si > Ge ≈ Sn

Explanation:

In group 14, as we move down from C to Sn, the size increases and electronegativity decreases. This results in the decrease in M – M bond energy. Hence the catenation property decreases.

Bond energy is the amount of energy required to fragment the atoms combined in a molecule are born into separate atoms. Carbon has maximum bond energy as compared to its other group elements. Therefore, shows maximum catenation property.
