Re: Why is this cis?
The molecule is cis because the two molecules with the highest priority are on the same side

Cis/trans system uses the longest carbon chain.

Re: Why is this cis?
Thank you but I'm
Still confused which moleculares are the highest priority? Versuses what other molecules are lowest priority?

I understand that but what I'm confused with is what molecules we are suppose to be analyzing here for their atomic number. Thank you

No, this is completely untrue. Cis/trans is completely different from E/Z. ONLY E/Z uses the atomic numbering system. For cis/trans, it either uses identical substituents or longest carbon chain. Just use E/Z for double bonds b/c there is too much confusion with cis/trans and double bonds.
Return to “*Constitutional and Geometric Isomers (cis, Z and trans, E)”
