Carbon and silicon both belong to the group 14, but despite the stoichiometric similarity, the dioxides, (i.e., carbon dioxide and silicon dioxide), differ in their structures. Comment.
Carbon in group 14 has the ability to form stable p-p bonds with itself and other elements of the first row.
With the link formed between the atoms is a double bond.
The silicon does not form p-p bonds easily and instead link by single covalent bonds due to its large nuclear size.
