P: 736 OK... We have 1,2,3,4,5,6-hexahydroxycyclohexane. A cyclohexane ring, with one -OH group on each carbon. Molecular formula: $$C_6 H_{12} O_6$$ (yes, a structural isomer of glucose!) The question: If all hydroxyls are in their equitorial positions, the name of the structure is 1,3,5/2,4,6 - hexahydroxycyclohexane (aka, scyllitol). Correct? I mean, is scyllitol the most stable stereoisomer of 1,2,3,4,5,6-hexahydroxycyclohexane ? If you wish, the question is "visually represented" in the image attachment Attached Thumbnails
