Anewly isolated natural product was found to have the molecular formula c15h28o2. by hydrogenating a sample of the compound, it was determined to possess one π bond. how many rings are present in the compound?

Hydrogenation reactions, in which h2 and an "unsaturated" organic compound combine, are used in the food, fuel, and polymer industries. in the simplest case, ethene (c2h4) and h2 form ethane (c2h6). if 140 kj is given off per mole of c2h4 reacting, how much heat (in mj) is released when 12 kg of c2h6 forms?
