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 ...
