(choose chapter or problem)

The organic molecules shown here are derivatives of benzene in which six-membered rings are “fused” at the edges of the hexagons.

(a) Determine the empirical formula of benzene and of these three compounds.

(b) Suppose you are given a sample of one of the compounds. Could combustion analysis be used to determine unambiguously which of the three it is?

(c) Naphthalene, the active ingredient in mothballs, is a white solid. Write a balanced equation for the combustion of naphthalene to

(d) Using the Lewis structure for naph \(\mathrm{CO}_{2}(g) \text { and } \mathrm{H}_{2} \mathrm{O}(g)\)  thalene and the average bond enthalpies in Table , estimate the heat of combustion of naphthalene in \(\mathrm{kJ} / \mathrm{mol}\).

(e) Would you expect naphthalene, anthracene, and tetracene to have multiple resonance structures? If so, draw the additional resonance structures for naphthalene. (f) Benzene, naphthalene,
