If you were relying on IR data alone,could you determine if you had the (+) or (-) form of carvone? why or why not? suggest one other method for detection.
If I were relying on IR data alone, I would not be able to determine whether I had the (+) or (-) form of carvone. Infrared (IR) spectroscopy provides information about the functional groups present in a molecule but not about the absolute stereochemistry or the chirality (the property of having a non-superimposable mirror image) of a compound.
To determine the (+) or (-) form of carvone, other methods such as polarimetry or chiral high-performance liquid chromatography (HPLC) are commonly employed. These techniques can measure the rotation of plane-polarized light by optically active compounds and thus differentiate between enantiomers.
One other method for detecting the (+) or (-) form of carvone is using nuclear magnetic resonance (NMR) spectroscopy. NMR can provide information about the spatial arrangement of atoms in a molecule, including chirality. By observing the splitting patterns of specific proton or carbon signals, one can identify the presence of chiral centers or the absolute stereochemistry of a compound.
