If three compounds, D, E, and F have the same molecular formula, C5H6. In the presence of a platinum catalyst, all three compounds absorb 3 molar equivalents of hydrogen also yield pentane. Compounds E and F give a precipitate while treated with ammoniacal silver nitrate compound D gives no reaction. Compound D and E show an absorption maximum near 230 nm. Compound F demonstrates no absorption maximum beyond 200 nm. Offer structures for D, E, and F.
