What would be the major difference between the IR spectrum of your aldol product and an IRspectrum of a mixture of vanillin and acetone? a) There would be two C=O stretches in the starting mixture, but not in the product.b) The C=O stretch in the product would be at lower frequency than acetone, as it is a highlyconjugated ketone.c) There would be an OH stretch in the starting mixture, but not in the product.d) Both a) and b)e) Both a) and c)
