define the the following
mezocompounds
diastereomers
racemic mixture
meso compound :- 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. This means that despite containing two or more stereocenters it is not chiral.
eg:-diastereomers :- if a compound has two optical center it can form 4 or more isomers. some of those isomers which are optical isomers but not enantiomers are diastereomers of each other.egracemic mixture:- Aracemic mixtureis the mixture of two isomers of a chemical structure in equal amounts.
