    Hi everyone, just a quick theoretical yield question..

    I completed a diels alder reaction where two products were made: an aldehyde firstly which was then synthesised to make a dicarboxylic acid, and I now have to calculate theoretical yields for both products.

    So far I've calculated the moles of the reagents used to synthesise the aldehyde and found the limiting reagent but I'm now unsure whether I multiply by the molecular mass of the aldehyde or the carboxylic acid?

    Do I multiply by the molecular mass of the aldehyde to find the aldehyde's theoretical yield, then multiply by the molecular mass of the carboxylic acid to find the second theoretical yield?

    Have you drawn out the mechanism and managed to show how many mol of aldehyde is produced by 1 eq of the limiting reactant and how many acid is produced from that eq amount of aldehyde produced? and if you can show that all the aldehyde will go to the acid via a sensible mechanism, theoretically, there shouldn't be any aldehyde left(assuming 100% conversion, of course).
