Question

Why carbon shows stronger catenation properties but silicon does not?

Answer 1

Answer:

The silicon atom is larger than the carbon atom, its covalent radius is 111 pm carbon is 77 pm which makes it more difficult for silicon to form a tetrahedral arrangement with other atoms. The Si-Si bond is also longer and weaker than the C-C bond.

HOPE THIS HELPS YOU!!

Answer 2

Answer:

because carbon has highest valency than silicon that's why the big chain will form
