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.

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?

Product was formed successfully based on the exp. below (about
85% yield), please interpret/discuss HNMR/IR in as much detail as
possible and assign peaks on HNMR (which peak represents which
protons of which group, etc). Note: I already know how you
determine the formation of the product so you can skip that part of
part b).
Based on this exp:
Discuss the IR spectrum and what is the peak in IR that you can see for a specific functional group...
