Chemists have made the all-cis isomer of 1,2,3,4,5,6-hexafluorocyclohexane, a crystalline ring molecule with all six fluorines pointing “up” and all six hydrogens pointing “down.” This compound is remarkable for being the most polar nonionic compound now known to exist, according to David O’Hagan of the University of St. Andrews, in Scotland. O’Hagan, whose team synthesized the compound, described the chemistry behind the molecule this week during a Division of Fluorine Chemistry symposium . . .
