State a reason for each of the following statements:
(i) Fluorine never exhibits any positive oxidation state.
(ii) Helium does not form any real chemical compound.
[Hint : (a) Due to inert pair effect.
(b) Due to more bond dissociation enthalpy of O H as compared to S H bond.
(c) Due to more steric hindrance...
In the first transition series, Cu exhibits +1 oxidation state very frequently. It is because Cu ( +1) has an electronic configuration of [Ar] 3d10. The completely filled d-orbital makes...

(i) Fluorine does not exhibit any positive oxidation state as it is the most electro-negative element and does not have d orbitals in its valance shell.
(ii) This is due to...
