The azide ion, N₃^–, is linear with two N–N bonds of equal length, 1.16 Å. (a) Draw a Lewis structure for the azide ion. (b) With reference to Table 8.5, is the observed N–N bond length consistent with your Lewis structure? (c) What hybridization scheme would you expect at each of the nitrogen atoms in N₃^–? (d) Show which hybridized and unhybridized orbitals are involved in the formation of σ and π bonds in N₃^–. (e) It is often observed that σ bonds that involve an sp hybrid orbital are shorter than those that involve only sp² or sp³ hybrid orbitals. Can you propose a reason for this? Is this observation applicable to the observed bond lengths in N₃^–?
