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 `gt` Si `gt` Ge `gt` SnB. C `gt gt` Si `gt` Ge `~~` SnC. Si `gt` C `gt` Sn `gt` GeD. Ge `gt` Sn `gt` Si `gt` C

Answer» Correct Answer - B
The tendency to form long open or closed atom chains by combination of some atoms in themselves is known as catenation. The catenation is maximum in carbon and decreases down the group
C `gt gt` Si `gt` Ge `~~` Sn `gt` Pb
This is due to high bond energy of C-C bonds. Down the group, size increases and electronegativity decreases, thereby, tendency to show catenation decreases.
