A sample contains a mixture of (+) and (-)- carvone. When you measure the optical rotation of the neat sample (no solvent) at 20°C using a polarimeter with a sodium lamp, you obtain an optical rotation of-31.2°. Calculate the optical purity and ratio of carvone enantiomers in your mixture given that the specific rotation of(-)-carvone is-62.5°at 20°C.

Specific rotation of L-alanine in water (at 25 °C) is +2.8. Suppose you have 3.00 g of mixture of L and D-alanine. You dissolved it in 10 mL of water, and measured rotation in 10 cm cell. The observed rotation was +0.12. Calculate the ee% for the mixture. How many grams of D- and L-alanine do you have in the sample? Optical purity (ee%) = observed specific rotation/ specific rotation of the pure enantiomer x 100= (+0.12 / +2.80 )...

An experiment was carried out to measure the effect of growth hormone on girls affected by a growth disorder called Turner’s syndrome. A total 68 girls participated in the study. Half of the girls were placed into the treatment group; these girls were given the active drug. The other half of girls were placed into the control group and were given a placebo with no active ingredients. Their heights were measured at the time the hormone was first administered and...
