Question

The reason for the distinct difference in the properties of CO2 and SiO2 is (A) Carbon is more electronegative than O and in case of SiO2 oxygen is more electronegative than silicon (B) Carbon has small size and forms a π bond with good overlap whereas silicon has larger size hence has a poor π -overlap (C) First ionization potential of carbon is higher than that of silicon (D) Carbon has only 'p' orbitals and lacks 'd' orbitals whereas silicon has 'd' orbitals

CO2 is a linear discrete gaseous molecule while SiO2 is a three-dimensional network solid as in CO2 π bond do not polymerised due to strong overlapping while in SiO2 π bond polymerised due to poor overlapping.

Q. The reason for the distinct difference in the properties of $C O_{2}$ and $S i O_{2}$ is

Carbon is more electronegative than O and in case of $S i O_{2}$ oxygen is more electronegative than silicon

Carbon has small size and forms a $π$ bond with good overlap whereas silicon has larger size hence has a poor $π$ -overlap

First ionization potential of carbon is higher than that of silicon

Carbon has only 'p' orbitals and lacks 'd' orbitals whereas silicon has 'd' orbitals
