Solution: Mothballs are composed of naphthalene, C10H8, a molecule that consists of two six-membered rings of carbon fused along an edge, as shown in this incomplete Lewis structure:Do you expect the C - C bond

Problem

Mothballs are composed of naphthalene, C10H8, a molecule that consists of two six-membered rings of carbon fused along an edge, as shown in this incomplete Lewis structure:
The structure appears as two six-membered rings, arranged with their points up and down.  Each vertex is a carbon, and the sides of the rings are single bonds.  The rings are fused on the right side of the left ring and the left side of the right ring, sharing that side.  All carbons except the two making up that fused side are also single bonded outside the rings to H.

Do you expect the C - C bond lengths in the molecule to be similar to those of C - C single bonds, C = C double bonds, or intermediate between C - C single and C = C double bonds?
