(a) Draw the structures of the following :
(b) Explain the following observations :
(i) In the structure of the N-O bond (121 pm) is shorter than the N-OH bond (140 pm).
(ii) All the P-Cl bonds in are not equivalent.
(iii) ICI is more reactive than
(a) (i) (Pyrosulphuric acid) or oleum :
(b) (i) The N-O bond has partial double bond character while the N-OH bond is a single bond in both resonance of
(ii) All the P-Cl bonds in are not equivalent due to the fact that the axial bond pairs suffer more repulsion as compared to equatorial bond pairs.
(iii) Because ICI bond is weaker than I-I bond as a result of which ICI breaks easily to form halogen atoms which readily bring about the reaction, hence more reactive.
