Which of the following symmetry element(s) can be found in the conformers of meso-2,3-dibromobutane ?
(A) POS (Plane of symmetry) (B) All of these (C) COS (Centre of symmetry) (D) AAOS (Alternate axis of symmetry)
Options:
Answer:
B
Solution:
Different conformers of meso-2,3-dibromobutane show different elements. The eclipsed/gauche-type conformers with the two Br on the same side have a plane of symmetry (POS = S1); the anti staggered conformer has a centre of symmetry (COS = S2), and a centre of symmetry is itself an alternating (improper) axis of symmetry S2 (AAOS). So all three can be found.
Ans. (B) All of these.
