Question- Suppose you were asked to carry out an aldol condensation reaction between benzaldehyde and pentanal, modeled after the experiment you performed with benzaldehyde and acetone. What product would you expect to make? Propose a detailed reaction mechanism for this reaction. What by-product(s) might be expected in this experiment?
If possible just a brief explanation how you got the answer?
