It means that the yield from the reaction of the desired product has been that percentage of what would ideally have been obtained if all the least abundant reagent present had been quantitatively converted to the desired product.

I could have sworn that I said "yield?" in a previous post? There was no picture then.

you are right ozone,

It just didn't click, usually yields are on products, of course it makes sense now.

Thanks for the replies
