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).

Experimental Outline In its simplest form, the aldol condensation is a self-addition involving two molecules of the same aldehyde or ketone, in the presence of a base, and results in the formation of a new carbon-carbon bond joining the carbonyl carbon of one molecule to the a-position of the second. In many cases - if the reaction conditions aren't sufficiently mild - the initially formed aldol product reacts further in an elimination reaction to give what is...
