Hey!!
Here is ur answer....
No, their structures are different.
It is because of the structure of the CO2 . Two of carbon's valence electrons hybridize into two spsp hybrid orbitals. As a result, the molecule is one dimensional with an angle of 180 between bonds and completely non-polar. The Si, on the other hand, does not form such bonds and the angle is far from 180°, which in conjunction with oxygens high electronegativity makes it quite polar. Thus the interaction between neighboring Siand O atoms of different SiO2 molecules is much higher and as a consequence you need much more energy to break the solid, giving it an increased melting point.
hope so you will be happy with my answer....please mark it.......please....
