Which statement is not true for a meso compound?
A)The specific rotation is 0.
B)There are one or more planes of symmetry.
C)A single molecule is identical to its mirror image.
D)More than one stereogenic center must be present.
E)The stereochemical labels,(R)and (S),must be identical for each stereogenic center.

Question

Quizplus · Accepted Answer

In a meso compound, there are multiple stereogenic centers, but they are arranged in such a way that the molecule as a whole is achiral. Therefore, while the stereochemical labels (R) and (S) may be present on the stereogenic centers, they will not be identical for each pair of stereogenic centers since a meso compound has two sets of enantiomers. Therefore, statement E is not true and is the best choice for this question.
