What is the limiting reagent and theoretical yield? (please show work step by step with units) This is an aldol reaction with acetone, benzaldehyde, NaOH (5M in 25 mL solution = 5g), and an ethanol solvent. There is a 2:1 ratio of benzaldehyde and acetone. 3g of acetone which I calculated to be .05 moles . Since it was 2:1 I assumed that meant there needed to be 0.10 moles of benzaldehyde that I calculated to be 10.16 g.
