Question

a) Draw a Lewis structure including all resonance structures and nonzero formal charges for the isolated azide anion, N₃^-

b) .Based on the Lewis structure, predict whether the two N-N bond lengths in the azide ion will be the same or different; if different, which one is longer; and whether the bond lengths are shorter or longer than those in N₂

c) Draw a Lewis structure including all resonance structures and nonzero formal charges for hydrogen azide, HN₃

d) Based on the Lewis structure, predict whether the two N-N bond lengths in hydrogen azide will be the same or different; if different, which one is longer; and whether the bond lengths are shorter or longer than those in N₂.

e) Predict the bond angles around the central N atoms in the azide ion and hydrogen azide.

f) The experimental for each N-N bond in the azide ion is 1.16Å. More information about the experimental structures of the azide ion and hydrogen azide is available in Wikipedia.

Compare your predictions in questions (a - e) to the information from those sources. Describe any differences, and provide a possible explanation.
