One source defines a meso compound as 'an achiral compound with stereocenters.' Why is this a poor definition?

Options:

Answer:
B
Solution:

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, yet nobody would call them meso. The definition therefore classifies ordinary cis/trans alkenes as meso compounds, which is wrong.

Ans. (B)
