Which of the following symmetry(s) are present in any conformer of meso tartaric acid ?
(A) POS (Plane of symmetry) (B) COS (Centre of symmetry) (C) AAOS (Alternate axis of symmetry) (D) All
Options:
Answer:
D
Solution:
Ans. (D) All.
Sol. In one of its staggered conformers meso-tartaric acid has a plane of symmetry (POS = S1); in the anti conformer it has a centre of symmetry (COS = S2), and a centre of symmetry is itself an alternating (improper) axis of symmetry S2, so AAOS is also present. Hence all three symmetry elements are found among the conformers of meso-tartaric acid.
