Homework Answers
The most contributing resonance structures of azulene involves
separation of charges in as both ring achieves aromaticity by
gaining 6 electrons.
Resonance structures of azulene:
Resonance hybrid:
This charge separation makes the molecule polar with a dipole moment of ~1.0 D.

Dehydration Experiment: 1. Show all appropriate electron-pushing arrows to explain the formation of each of the observed products in the following reaction. Because intermediates have been provided for you, all arrows must be perfect and must be clear to get credit. 9M H,SO 20- s-d-o g- 2. "Rearrangements" like you see above are fairly common in Snl (and El) reactions, but are never seen in Sy2 or E2 reactions. Why don't those latter mechanisms ever allow rearrangement to occur?
