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).

Rheosmin is a saturated ketone obtained from an
alpha,beta-unsaturated ketone (a crossed aldol condensation
product) which is capable of undergoing hydrogenation to yield a
saturated ketone (Rheosmin). Using this technique, identify the
reagents needed to prepare Rheosmin via crossed aldol reaction.
