2d


Remember, enantiomers are mirror images.
Are cis and trans isomers really mirror images of each other?

Thanks, I thought it would be due to the change in connectivity in space. Or am I confusing concepts?

I suppose you mean different orientation, since different connectivity implies constitutional isomerism.

Cis trans isomers are diastereomers since they are not mirror images of each other (if you reflect the cis isomer, you cannot get the trans isomer).

Hey Dan, Why would 2a be incorrect. SHouldnt only the dash / wedges change positions in order to be considered an enantiomers?

Also Cat not quite sure what you mean?

How does a differ from b, fundamentally, e.g. replace the ammonium ion with fluorine, the hydrogen with bromine and so on?
