Question

Catenation i.e., linking of similar atoms depends on size and electronic configuration of atoms the tendency of catenation in group 14 elements follos the order.

• A. C > Si > Ge > Sn
• B. C>> Si > Ge $\approx$Sn
• C. Si > C > Sn > Ge
• D. Ge > Sn > Si > C

Answer 1

Answer: (B)

C>> Si > Ge $\approx$Sn

Answer 2

: As we go down the group, the atomic size increases and electronegativity decreases and thereby, tendency to show catenation decreases. Hence, the order of catentation is C >>Si> Ge $\approx$ Sn.
