    It is diene, no idea what you wrote - seems completely unrelated.

    Technically correct IUPAC name is probably but-1,3-diene, but I am not going to pretend I am expert on organic nomenclature.

    That is correct, 'ene' though, not 'ede'

    Somehow I fail to see "prefix" between di and ene.

    Yea completely fell asleep on that reply, prefix before diene.
