Identify which of the following compounds is a meso compound.
(a) 
(b) 
(c) 
Options:
Answer:
C
Solution:
Ans. (C) (a, c).
Sol. (a) The 1,2,4,5-tetramethylcyclohexane shown has a plane of symmetry through the opposite ring carbons carrying the vertical substituents, so it is meso. (b) trans-1,2-Dibromocyclopentane has no plane or centre of symmetry: chiral, not meso. (c) The butane-2,3-diol shown has a plane of symmetry between C2 and C3 (the two stereocentres are opposite in configuration), so it is meso.
