Is methylcyclohexane chiral? Socratic

Webmeso compounds certainly can have chiral centers, but for this one, if you look at the carbons that bear the substituents, when you go around the ring to assign priority, you will see that each direction around the ring is the same, so they are of equal priority, meaning there are no chiral centers. something like cis-1,3-dichlorocyclohexane is an example of … WebSep 7, 2016 · I'd like to expand the discussion somewhat by detailing how digraphs and Cahn-Ingold-Prelog- (Helmchen) rules account for the ZR and ES assignments for 1-ethylidene-4-methylcyclohexane.
