identical: is the exact same, this is the **top right**, which has just been flipped over so the ups are down and downs are up. enantomer: - mirror image **bottom middle**, flip it over up and down is the same, but side-to-side is reversed - or leave it how it is and place it directly on top of the reference and up and down are opposite but the species match exactly diastereomer: **top left** everything is in the correct order. Not mirror image since para OCH3 and OH are trans in reference molecule structural: different bonding order **bottom left** broke the ring adds two Hs formed double bond subtracts two Hs conformational:this is basically identical, just rotation about single bond **top middle** where the top OH just needs to spin around the top C What is the bottom right? Is is a mirror image with conformational. This would be diastereomer. different compound that is not isometric: they seem to all be isomers Solution identical: is the exact same, this is the **top right**, which has just been flipped over so the ups are down and downs are up. enantomer: - mirror image **bottom middle**, flip it over up and down is the same, but side-to-side is reversed - or leave it how it is and place it directly on top of the reference and up and down are opposite but the species match exactly diastereomer: **top left** everything is in the correct order.
