Some of the pairs of drawings below represent energetically nonequivalent isomer

Question

Some of the pairs of drawings below represent energetically nonequivalent isomers. Others either show two different ways of representing identical species or else are resonance structures for die same molecule. If 2 drawings show a pair of resonance structures, draw a double-headed arrow doubleheadarrow between them. If 2 drawings are just two different ways of representing identical species, circle them. If 2 drawings represent energetically nonequivalent isomers, draw a box around the one that should be more stable. In this case, write next to that pair whether they are constitutional isomers, stereoisomers, or conformational isomers.

Explanation / Answer

A. Double headed arrow (resonance)

B. circle (same structure drawn in different reprentation)

C. The right one should be more stable, a box should be drawn there. Ring strain is more in cyclobutane.

D. The right one should be more stable, a box should be drawn there. The methyl are oriented in opposite direction are more stable.
