The two terms racemic mixture and meso compound are used in organic chemistry to describe different organic compounds.A racemic mixture is also known as a racemate.It is a mixture of equal amounts of left and right-handed enantiomers.Enantiomers are optical isomers that are non-superimposable mirror images of each other. Meso form cannot be separated into optically active components because this form is a single substance and not a mixture. Correct expression of enthalpy of combustion isatomcity[NCERT Pg. Because of these, it is optically inactive. What did women and children do at San Jose? It is a conjugate acid of a meso-tartrate(1-). As we have two mirror images in the molecule itself ,it can't exhibit optical isomerism. Its angle of optical rotation is also 0°. The three stereoisomers of tartaric acid are all different. Manipulate the model to convince yourself that the Newman projections of tartaric acid are the same structures as the ‘zig zag’ structures below. It can not be separated into two forms. A meso compound or meso isomer is a non-optically active member of a set of stereoisomers, at least two of which are optically active.

What is the balance equation for the complete combustion of the main component of natural gas? Anyone know how to draw a picture of an unsaturated solution of potassium? Optical inactivity of meso -tartaric acid We usually come across in many standard text books of organic chemistry that meso -tartaric acid is optically inactive simply because it has a plane of symmetry [11-13] (point group Cs) and an imaginary mirror plane is drawn across the molecule in a Fischer projection as shown in Fig. Only in the meso compound an internal plane of symmetry exists, bisecting the molecule which is not present in the non-meso compounds. The last is called the meso form and is superposable with its mirror image. This is also known as internal compensation.
