TestHub · Accepted Answer

Quercitol is cyclohexane-1,2,3,4,5-pentol: five stereocentres on a symmetric ring (one ring carbon carries two H). Enumerating the 2⁵ = 32 up/down patterns modulo the ring symmetries gives 16 distinct configurations; 12 of them are chiral (six enantiomeric pairs) and the remaining 4 have an internal plane of symmetry (meso).

Ans. (B) Total stereoisomers = 16, meso = 4.
