We are being asked to identify the resonance forms of naphthalene, C10H8.
First, we will have to draw the Lewis Structure of C10H8.
Step 1: Calculate the total number of valence electrons present.
Group Valence Electrons
C 4A 4 valence e‑ x 10
H 1A 1 valence e- x 8
Total = 48 valence e-
Step 2: Draw the Lewis Structure for the molecule
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:
Draw all of the resonance structures of naphthalene. How many are there?
