    Could anyone tell me what the 'x' bonds in this molecule are?



    Oh, I guess they're undefined double stereo bonds. I knew where to learn that, but could someone explain what they are exactly?

    You're right, it's down to undefined stereochemistry of the double bond (cis or trans)

    So they mean that there could either be a cis or trans bond there, and it's not known which, or does it mean that it could be either cis or trans, and it's still treated as the same molecule, perhaps...?

    Yeah, pretty much. I'm not an organic chemist but I imagine it'd be useful when you're drawing out a reaction scheme for some reaction where the selectivity isn't known or if you get a mixture of isomers, like... some E1 reactions I'd imagine...
