The correct order of catenation tendency of `14^(th)` group elements

A

`C gt Sn gt Si ~~ Ge`

B

`Si gt Sn gt C gt Ge`

C

`Ge gt Sn gt Si gt C`

D

`C gt Si gt Ge ~~ Sn`

Text Solution

Verified by Experts

The correct Answer is:
D
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 Si gt Ge ~~ Sn`
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.
