Are diastereomers optically active?
Not necessarily , the meso form is optically inactive.
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.
What is difference between a racemic mixture and a meso compound?
Both are optically inactive, but for different reasons. A racemic mixture contains chiral molecules that, individually, are optically active. But the mixture contains optically active enantiomers, which essentially cancel out each other's optical activity (one enantiomer rotates light one way, the other rotates it back). A meso compound, however, is optically inactive on its own. It can have chiral centers within its structure, but due to symmetry it will still be optically inactive.
What does optically active mean in organic chemistry?
Optically active compounds which have one or more asymmetric carbon atoms. These carbon atoms are called chiral carbon. These atoms are sp3 hybridized.
Is phenylmethanol optically active?
No, it is not optically active.

Racemic mixtures and meso compounds?
solution containing equal amounts of enantiomers.it is optically inactive.

No, it is not optically active.
Is allene optically active or not?
Allenes are optically active.
What is asymmetrical symmetry?
The synthesis of an optically active compound from an optically inactive compound with or without using an optically active reagent.
What is chiral purity?
Chiral compounds are optically active, that means they rotate polarized light to the left or to the right depending on their configuration
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.
What has the author R R Chirumamilla written?
R. R. Chirumamilla has written: 'Studies on fermentative production of chiral compounds for optically active pharmaceuticals'
What are mesostructures?
a meso structure is a structure which has more than 1 chiral centers and is superimpossible on its miirror image.this compounds are optically inactive and can be reffered to as distereomers
