A stepwise mechanism for the formation of salsolinol in the given reaction is to be drawn. Concept introduction: A nucleophilic addition reaction takes place rapidly when carbonyl carbon is more electrophilic. An acid catalyzed reaction makes carbonyl carbon more electrophilic towards the nucleophilic attack.Both aldehydes and ketones yield imines or enamines, when they are treated with amines in the presence of mild acid.

Ethyl butyrate, CH3CH2CH2CO2CH2CH3CH3CH2CH2CO2CH2CH3, is an artificial fruit flavor commonly used in the food industry for such flavors as orange and pineapple. Its fragrance and taste are often associated with fresh orange juice, and thus it is most commonly used as orange flavoring. It can be produced by the reaction of butanoic acid with ethanol in the presence of an acid catalyst (H+H+): CH3CH2CH2CO2H(l)+CH2CH3OH(l)H+⟶CH3CH2CH2CO2CH2CH3(l)+H2O(l)CH3CH2CH2CO2H(l)+CH2CH3OH(l)⟶H+CH3CH2CH2CO2CH2CH3(l)+H2O(l) A chemist ran the reaction and obtained 5.40 g of ethyl butyrate. What was the percent yield, The chemist discovers a more efficient catalyst that can produce ethyl butyrate with a 78.0% yield. How many grams would be produced from 7.45g of butanoic acid and excess ethanol?
