Nitrogen forms several oxides. Why?

Which does not form a Pentahalide?

(A): C Cl_(2) does not undergo hydrolysis where as SiCl_(4) is readily hydrolysed. (R) : Carbon has no d-orbitals in its valence shell, but silicon has vacant d-orbitals in its valence shell.

Passage-IV : Sulphur and rest of the elements of group 16 are less electronegative than oxygen. Therefore, their atoms cannot take up electrons easily. They can acquire ns^(2)np^(6) configuration by sharing two electrons with the atoms of other elements and thus, exhibit +2 oxidation state in their compounds. In addition to this, their atoms have vacant d-orbitals in their valence shell to which electrons can be promoted from the p and s-orbitals of the shell. As a result, they can show +4 and +6 oxidation states shell. Like sulphur, oxygen does not show +4 and +6 oxidation states. The reason is :
