You were asked to separate compounds A, B, and C extracted from a plant material through steam distillation. In your experiment, you were able to collect three distillates at different temperatures. In order to classify the compounds in each distillate, you performed several physical and chemical tests. The results are tabulated below. Based on the Results, what are the identities of the terpenoids in each distillate?
