Question

please tell the answer​

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.

Answer 2

........ because catenation is the linkage of atoms of the same element into longer chains. Catenation most readily occurs in carbon which forms covalent bonds with other carbon atoms to form longer chains and structure.C with the least diffuse p orbital can form a longer p-p sigma bond. This sigma overlap is strong enough to form stable C-C long chains.

I hope this help you.
