MCQ
The correct order of catenation is
A
$C > Sn > Si \approx Ge$
B
$Ge > Sn > Si > C$
C
$Si > Sn > C > Ge$
✓
$C > Si > Ge \approx Sn$
✓
Answer
Correct option: D.
$C > Si > Ge \approx Sn$
d In this order of catenation is asked. Catenation is a self-linking property here and for group $14$ : Self-linking is through covalent bonding $C > Si > Ge \approx Sn$ In $C$ there is $2p -2p$ overlapping further $3p -3p, 4p-4p$ and so on and the extent of overlapping is more in $2p-2p > 3p-3p > 4p-4p \approx 5p-5p$
