A meso compound or meso isomer is an optically inactive isomer in a set of stereoisomers, at least two of which are optically active. [1] [2] This means that despite containing two or more stereocenters, the molecule is not chiral. A meso compound is superposable on its mirror image (not to be confused with superimposable, as any two objects ...
These include meso compounds, cis–trans isomers, E-Z isomers, and non-enantiomeric optical isomers. Diastereomers seldom have the same physical properties. In the example shown below, the meso form of tartaric acid forms a diastereomeric pair with both levo- and dextro-tartaric acids, which form an enantiomeric pair.
Of the three stereoisomers, two are enantiomers (levo- and dextro-2,3-butanediol) and one is a meso compound. [ 1 ] [ 2 ] The enantiomeric pair have (2 R , 3 R ) and (2 S , 3 S ) configurations at carbons 2 and 3, while the meso compound has configuration (2 R , 3 S ) or, equivalently, (2 S , 3 R ).
However, since all other isomers are meso (non-chiral) compounds, the name myo-inositol is now preferred (myo- being a medical prefix for "muscle"). Inositol was once considered a member of the vitamin B complex, namely vitamin B 8 before the discovery that it is made naturally in the human body, and therefore cannot be a vitamin or essential ...
The compound exists as three stereoisomers, a pair of enantiomers and the meso isomer. All are colorless liquids. Preparation and reactions 2,3 ...
In chemistry, isomers are molecules or polyatomic ions with identical molecular formula – that is, the same number of atoms of each element – but distinct arrangements of atoms in space. [1] Isomerism refers to the existence or possibility of isomers.
From the meso-isomer, typical nickel complexes contain two such ligands, i.e. [Ni(P R 2 NR') 2] 2+. When bound to metals, these ligands adopt a conformation similar to that of 1,4-diazacycloheptanes. Acyclic phosphine-amine ligands have the formula (R 2 PCH 2)NR'.
