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 » Sn
(c) Si > C > Sn > Ge (d) Ge > Sn > Si > C

Answer 1

Explanation:

The order of catenation is C > > Si > Ge ~ Sn

Answer 2

Answer:

(b) C > Si > Ge > Sn.

Explanation:

Down the group, atomic size increases and electronegativity decreases. Therefore tendency of catenation decreases down the group as follows C > Si > Ge > Sn.
