What is the expected mass of the product of the reaction of 0.0015 moles of 3,4-dimethoxybenzaldehyde and 0.0015 moles of 1-indanone with 0.05g of solid NaOH and addition of HCl solution afterwards? This is an aldol condensation (green chemistry) problem.

Aldol Condensation (multi-part question) 1. a. Why does mixing of solid 3,4-dimethoxybenzaldehyde and solid 1-indanone result a liquid solution? b. Why is the condensation (dehydrated) product rather than the aldol addition (hydrated) product obtained in this experiment? (What makes the condensation product exceptionally stable?) c. Why does the enolate ion of an aromatic ketone react faster with an aldehyde group (producing a crossed-aldol reaction) than with the carbonyl group of another molecule of ketone?

How would I calculate theoretical yield and furthermore, the
percent yield? This experiment had a lot of chemicals used and I
don't know where to start.

possible and assign peaks on HNMR (which peak represents which

determine the formation of the product so you can skip that part of

Lab : Aldol Condensation Purpose. In this lab you will conduct the Aldol condensation reaction under solid-state reaction conditions that will involve grinding reactants in the solid phase. You must read ahead and learn about this reaction and the chemical mechanism for the Aldol condensation. There are two possible products which are the initial Aldol or subsequent elimination product. You will need to isolate and purify your reaction product. You will use your melting point, IR, 1H and 13C NMR spectra to...
