Each half of the meso compound is the mirror image of the other half and cancels the optical activity of the other thus the molecule is achiral.

Meso compounds example. We call the substituents which lead to this result meta- directorsExamples of meta directors include nitriles carbonyl compounds such as aldehydes ketones and esters sulfones electron-deficient alkyl groups nitro groups and alkylammoniums. An example of such an enantiomer is the sedative thalidomide which was sold in a number of countries around the world from 1957 until 1961It was withdrawn from the market when it was found to cause birth defects. One enantiomer caused the desirable sedative effects while the other unavoidably present in equal quantities caused birth defects.

A meso compound is not superimposable upon its mirror image A meso compound contains a plane of symmetry A meso compound contains no chirality centers A meso compound is optically inactive A meso compound is achiral. Nitration of trifluoromethylbenzene gives the meta product in about 90 yield. B an internal mirror plane bisecting the molecule.

Select all that apply. Which of the following statements correctly describe a meso compound. The herbicide mecoprop is a racemic mixture.

While soap is an emulsifier detergents tackle oily greasy organic soiling mainly because they are surfactants which lower the surface tension of the water and increase the solubility of organic compounds. Whether a perfume fragrance comes from a flower or a lab the molecules you smell and enjoy are an example of organic chemistry. Hydroxide is a diatomic anion with chemical formula OH It consists of an oxygen and hydrogen atom held together by a single covalent bond and carries a negative electric chargeIt is an important but usually minor constituent of waterIt functions as a base a ligand a nucleophile and a catalystThe hydroxide ion forms salts some of which dissociate in aqueous solution liberating.
