Answer in Organic Chemistry for bibi #268332
could you please help me answer these questions ASAP.
Use ChemDraw for all chemical structures (ACS document 1996 settings)
1) s- limonene has a specific optical rotation of 94 degree.the commercially supplied mixture of the latter has a 95% enentiometric excess (ee)
1a) what is a chiral centre in organic chemistry?
1b)Draw the R-enantiomer of limonene?
1c)what effect does R-limonene have on plane polarised light?
1d) what is the observed specific rotation of the above commercial mixture?
1e)what percentage of each enantiomer is present in the above commercial mixture (95% ee in favour of S)
1f)The S enantiomer has a characteristic smell of lemons, why does the R enantiomer smell of a different fragrance, that of oranges?
A chiral center of an atom is the atom in a molecule that is bonded to four different chemical species. Remember that a chemical species is an atom/molecule with a specific molecular structure.
rotates the plane of polarized light to the right, whereas the other rotates it to the left.
