- A mixture contains equal amounts of compounds A–D. a.Which compounds alone are optically active? b. If the mixture was subjected to fractional distillation, how many fractions would be obtained? c.How many of these fractions would be optically active?The LD50 (“Lethal Dose, 50 %”) is a value used in toxicology which gives the amount of a substance required to kill 50 % of a test population. It is usually reported based on body weight. For racemic carvone LD50 is reported as 1640 mg/kg. 1. Would it consider carvone to be toxic to an average person? Explain. 2. Would it be expected this the LD50 value to be the same for each enantiomer? Explain at the molecular level in stereochemical terms.Q1. What are emulsions? Why do they form during extractions? How is their formation minimized? Q2. Why is it necessary to turn the separatory funnel upside down and to open thestopcock?
