Which of the following statements about the interstitial compounds is incorrect?
They retain metallic conductivity
They are chemically reactive
They are much harder than the pure metal
They are much harder than the pure metal
Which one of the following molecules contains no pi -bond?
CO2
H2O
SO2
SO2
B.
H2O
All the molecules have O atom with lone pairs, but in H2O the H atom has no vacant orbital for pi-bonding. That's why it does not have any pi- bond.
In all other given molecules, the central atom because of the presence of vacant orbitals is capable to farm Pi- bonds.

MeSiCl3
Me2SiCl2
Me3SiCl
Me3SiCl
