Question

The correct order of catenation is

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

Answer 1

The correct option is C $C>Si>Ge\approx Sn$

The tendency to link with one another through covalent bonds to form chains and rings is known as catenation property.
It is an unique property of group 14 elements. Down the group, the size increases, tendency to show catenation decreases.

The order of catenation:
$C>>Si>Ge\approx Sn$

Lead does not show catenation
