Question

What kind of bonding is involved in carbon dioxide and silicon dioxide?

Answer 1

Hint : Chemical bonding is the development of a chemical compound by forming a chemical bond between two or more atoms, molecules, or ions. The atoms in the resulting compound are held together by chemical bonds.


Complete Step By Step Answer:
\[C{O_2}\], or carbon dioxide, is a colorless gas with a density around \[53\] percentage higher than that of dry air. In the Earth's atmosphere, it exists as a trace gas. Silica, also identified as silicon dioxide, is an oxide of silicon with the chemical formula \[Si{O_2}\] . It is most commonly found as quartz in nature and various living organisms.
The bonding of carbon dioxide and silicon dioxide exemplifies an exciting phenomenon in terms of molecular and non-molecular bonding.
Carbon dioxide is a chemical compound with the Lewis form \[O = C = O\] . The central carbon has been \[sp\] hybridized, while the terminal oxygens have been \[s{p^2}\] hybridized.
\[Si{O_2}\] on the other hand, is non-molecular. It has an infinite number of \[Si - O - Si - O\] bridges. The third-row silicon atom has a lower capacity for \[p\pi - p\pi \] multiple bonding. So instead of single molecules, we have a massive covalent structure.

Additional Information:
At equilibrium, the carbon dioxide molecule is linear and centrosymmetric. The silicon atom is tetrahedral coordinated in the majority of silicates, with four oxygen atoms surrounding a central \[Si\] atom.

Note :
When multiple atoms bind covalently to form a new species, each particle is referred to as a molecule, and the molecules are referred to as a molecular compound collectively. A substance can be atomic or ionic if it is not molecular. Although these substances have several atoms bound to one another, the bonds are not covalent, and therefore the substances are not molecular.
