Lab report gas chromatograph and optical activity carvones

Optical activity of carvones essay sample abstract: the objective of this experiment is to use gas chromatography to distinguish between two enantiomers of carvone from caraway oil and spearment oil and to find the 2 carvone’s optical activity as well as percent carvone in spearment and caraway oil. Both of the enantiomers have the same exact density, boiling/melting point, color, viscosity, ir spectra, indices of refraction, and thin-layer/gas chromatography although it may seem that they have almost everything in common, they each exhibit a different optical activity that is due to the chiral center.
