Why SiO2 is not linear as CO2?

But why the molecular shape of SiO2 is linear? Because there is no lone pair present on the central atom of the SiO2 lewis dot structure. So, there is no repulsion occur between bond pair and lone pair electrons around the central atom.

Why is SiO2 different from CO2?

The key difference between SiO2 and CO2 is that the SiO2 exists in solid phase whereas, the CO2 exists in gaseous phase at standard temperature and pressure conditions. SiO2 is silicon dioxide. Both silicon and carbon are group 14 elements in the periodic table of elements.

Does SiO2 have linear structure?

The electron arrangement and molecular shape are both linear. Since SiO2 has two places of electron concentration and no lone pairs, it is linear.

Why is CO2 a linear shape?

1. Carbon dioxide is linear, while sulphur dioxide is bent (V-shaped). In the carbon dioxide, the two double bonds try to get as far apart as possible, and so the molecule is linear.

Why is CO2 gas but SiO2 solid?

In $C{O_2}$ there is a double bond between carbon and oxygen atoms. Carbon has a tendency to make bonds with oxygen but silicon cannot make bonds with oxygen due to which it forms a giant molecular network with oxygen. Due to this the bonding in this molecule is very strong and hence it exists as solid.

Which out of CO2 and SiO2 is a molecular solid?

Silicon dioxide is network solid due to strong intermolecular covalent bond. In carbon dioxide, the molecules are bonded by weak van der Walls force. Hence, they are molecular solids. So, the correct answer is option C.

Why does CO2 have a linear structure?

Answer Wiki. CO2 has a linear structure because it has no lone pair electron.The Lewis structure, carbon is bond by double bond oxygen making it two pairs electron.

Why is the shape of SiO2 molecule bent?

Hence the linear geometry is disturbed to give a bent shape to SiO2 molecule. In CO2 there is no lone pair on the central atom (Carbon). Thus, no such phenomenon occurs. So the CO2 molecule is linear.

What is the molecular geometry of carbon dioxide?

Carbon dioxide has a linear molecular geometry given that it’s bond angle is 180° between both carbon and the two oxygen atoms.

Why doesn’t SiO2 show resonance as in CO2?

Hence the linear geometry is disturbed to give a bent shape to SiO2 molecule. In CO2 there is no lone pair on the central atom (Carbon). Thus, no such phenomenon occurs. So the CO2 molecule is linear. Why doesn’t SiO2 show resonance as in CO2? First of all, SiO2 is not actually SiO2, it’s a monomer of a polymeric network.
