CHM 102 P block elements Objective Question

Take CBT

Which of the following describes a key difference in catenation between Carbon and Silicon?

A Carbon forms -C-C-C- chains, while Silicon forms -Si-Si-Si- chains.

B Carbon can only form linear chains, while Silicon forms branched chains.

C Carbon forms -C-C-C- chains, while Silicon primarily forms Si-O-Si-O chains in silica (SiO₂).

Correct Answer

D Neither Carbon nor Silicon exhibits catenation to a significant extent.

Option C is the correct answer.

Page 24 states: 'Carbon can catenate. (forms -C-C-C- C- chains)' and 'Silicon forms only Si-O-Si-O chains in silica SiO₂.'

Recall the unique bonding characteristics of carbon and silicon related to chain formation.
