    What does the slash mean in synthetic route?

    e.g. LiAlH4/dry ether for reduction

    It means that both of these are used. In this case the lithium aluminium hydride is used in a dry ether solvent.

    Why do they use / instead of "and"?

    So does " reflux/distil " as conditions for making ketone from secondary alcohol in Edexcel mark scheme mean that we should reflux then distil? instead of reflux or distil?

    Thanks!

    When you're planning multi-step syntheses, it gets rather tedious having to write 'and' all the time so it's just used for convenience.

    If it's on a mark scheme it will have a completely different meaning to a / on a scheme ...

    Either answer would be correct I think (i.e. reflux or distil)

    Mark schemes separate alternative possible answers with a slash. This means that either answer is acceptable.
