    Hi, anyone know how many stereoisomers does dibenzalacetone has?

    I'm not a specialist in organic chemistry, but a simple count reveals 9 ordinary isomers (if you keep the ketone in the center). This assumes that it is possible to reposition the benzenes around the carbon chain, among which I strongly suspect some would be a lot more unstable than others.

    For stereoisomers, it appears to have only one.

    I counted to be 3 stereoisomers. cis-cis, cis-trans, trans-trans. Are there anymore steroisomers other than that?
