Chirality and Carvone Lab Procedure
16 A
Analysis of Spearmint and Caraway Oils
1. Smell the caraway and spearmint tubes, as well as the 2 carvones. Write down what you smell
Gas Chromatography
2. Find retention times of the oils by getting the composition percent
Polarimetry
3. Find the optical rotation alpha of both carvone samples; specific rotation or alpha d can be found from the observed rotation in degrees, the concentration in g per mL of the used solution, the length of the tube that is being used for the sample, and the wavelength(D), and the temperature used : [alpha]tλ = alpha / (concentration)(temperature)
Infared Spectroscopy
4. Get 2 NaCl plates and a holder, and only touch the sides of the plate, and make sure it is dry.
5. Put
