Mothballs are composed of naphthalene, C10H8, a molecule of which consists of two six-member rings of carbon fused along an edge, as shown in this incomplete Lewis structure:

(a) Write two complete Lewis structures for naphthalene.
(b) The observed C-C bond lengths in the molecule are intermediate between C-C single and C == C double bonds. Explain.
(c) Represent the resonance in naphthalene in a way analogous to that used to represent it in benzene.
