How many isomers in menthol?
Since each menthol isomer has 3 stereocenters, menthol has a total of 8 stereoisomers.
How many stereoisomers for muscarine?
muscarine has three stereocenters (aka chirality centers) therefore: 2^3=8 in conclusion, muscarine can have 8 stereoisomers.
How many chiral centers in progesterone?
6 stereocenters 8 s 9 s 10 r 13 s 14 s 17 s
How many total stereoisomers are there in cholesterol?
there are 128 stereoisomers of cholesteol . from the formula 2^n where n is the total number of chiral centers. As for cholesterol, there are 8 stereocenters therefore 2^8= 128
Why meso compounds are optically inactive?
A meso compoundis a molecule with multiple stereocenters that is superimposable on its mirror image. These particular traits lead to specific qualities that meso compoundsdo not share with most other stereoisomers. One such quality is the internal mirror plane. Optically inactive compounds are any that cannot be superimposed on itself.
Who has attended college the longest?
The answer is Timothy McLaurin. He spent 26 years and 4 months at 9 different Universities, earning 430 semester hours. He sat out 3 years of the 26 years and 4 months, yet went to summer school (in college) 10 times. He started at age 18 and went until age 44, and soon thereafter, developed the 'Best' Chemistry Method for assigning Absolute Configuration to stereocenters of Organic Chemical Structures, of which, the method is located at AbsoluteConfiguration.Org
Why is mesotartaric acid optically inactive?
Despite of containing two stereocenters (chiral centers) meso-tartaric acid is not chiral, because it is not stereospecific in the center of the molecule as a whole.A meso compound is superposable on its mirror image, and it does not produce a "(+)" or "(-)" reading when analyzed with a polarimeter.For example, of the 3 possible isomers of tartaric acid (depicted in 'Related links'), there is one mesocompound (the 2R,3S and 2S,3R isomers are equivalent) and two other optically active stereo-isomeric forms:dextrotartaric acid (L-(R,R)-(+)-tartaric acid) andlevotartaric acid (D-(S,S)-(-)-tartaric acid).Only in the meso compound an internal plane of symmetry exists, bisecting the molecule which is not present in the non-meso compounds. That is, on rotating the meso compound by 180° on a plane perpendicular to the screen, the same stereochemistry is obtained.
