Chemistry - STEREO ISOMERISM Question with Solution | TestHub

I and II are the diequatorial and diaxial trans-1,4-dimethylcyclohexane chairs, related by a ring flip. III and IV are the one-axial, one-equatorial cis-1,4 chairs, also related by a ring flip. The trans and cis sets are geometrical isomers. Thus I/III and II/IV are geometrical pairs, while I/II and III/IV are conformational pairs. All A,B,C,D are correct.
