1.What is the function of ethanol in this aldolcondensation?

A.Ethanol is the solvent for the reaction.

B.None of the answers shown are correct.

C.Ethanol is used to remove a proton from the carbonyl group of3,4-dimethoxybenzaldehyde.

D.Ethanol is the recrystallization solvent.

2.Assume the two reactants were in equimolar amounts to beginwith but you used 2.0 g of 1-indanone in the reaction instead of0.20 g, how might this affect your final yield?

A.Yield would be doubled.

B.YIELD WOULD NOT BE AFFECTED

C.YIELD WOULD DECREASED BY A FACTOR OF 10

D. YIELD WOULD INCREASE BY A FACTOR OF 10

3.Assume the sodium hydroxide has been setting out on the labbench open to the atmosphere for a period of time before you add itto the test tube. How might this affect your yield?

A. YIELD WOULD LIKELY DECREASE

B. YIELD WOULD INCREASE

C. YIELD WOULD NOT BE AFFECTED, BUT RATE OF REACTION WOULDDECREASED

D. YIELD WOULD NOT BE AFFECTED

4.What might be the result if you did not use enoughhydrochloric acid and the final pH remained above 7?

A.Yield would remain the same, but purity of the product woulddecrease.

B.Yield would likely increase and the purity of the productwould increase.

C.Yield would remain the same, but purity of the product wouldincrease.

D.Yield would likely decrease and the purity of the productwould decrease.

5.What might be the result if you did not grind the two initialreactants sufficiently?

A.Yield would decrease, but purity would not be affected.

B.Both yield and purity would decrease.

C. Yield would not be affected, but purity would bedecreased.

D. Neither yield nor purity would be affected.

6.To what does the term \'aldol\' refer in aldolcondensation?

A. The formation of a product from aldehyde and alcoholreactants.

B. The formation of a carboxylic acid.

C. An EAS mechanism.

D. The reactants both contain the aldehyde and alcoholfunctional groups.
