"WebApr 21, 2015 · trans-1,2-Dichlorocyclobutane has two chiral carbon atoms, and it lacks an internal plane of symmetry. It is not superimposable on its mirror image, so it exists at two enantiomers: ( 1R,2R )-1,2-dichlorocyclobutane and ( 1S,2S )-1,2-dichlorocyclobutane. Thus, only two of the isomeric dichlorocyclobutanes are optically active. Answer link " - How many carbons are in cyclobutane
