One source defines a meso compound as 'an achiral compound with stereocenters.' Why is this a poor definition?
Options:
Answer:
A
Solution:
Ans. (A)
Sol. A stereocentre is any atom at which the interchange of two groups produces a stereoisomer - this includes the sp2 carbons of alkenes that give cis-trans isomerism. cis- and trans-but-2-ene are achiral and each contains two stereocentres, so they satisfy the proposed definition, but they have no chiral diastereomer and are not meso compounds. A meso compound is an achiral compound with chirality (asymmetric) centres.
