Compound A is a clear, colorless liquid with a molecular formula of C7H10. Upon treatment of A with H2 gas in the presence of Pd on carbon, a single product B (C7H14) is obtained. Compound A has a λmax at 232 nm in its UV spectrum but will not react with any dienophile in a Diels-Alder fashion. Provide a structure for Compound A, and explain how you arrived at your decision.
