Worked Solution & Example Answer:An esterification reaction is to be performed - HSC - SSCE Chemistry - Question 7 - 2018 - Paper 1
Step 1
Which of the following substances, when added, would increase the yield of the product?
Answer
In esterification reactions, the addition of more reactants typically shifts the equilibrium towards the product side, thereby increasing the yield.
Analysis of Options:
- A. Water: While water is a product of esterification, adding it does not increase the yield of the ester. Instead, it could shift the equilibrium backward.
- B. Boiling chips: These are used to facilitate boiling and do not contribute to the yield of the ester.
- C. More alkanol: Adding more alkanol (the alcohol component in esterification) would increase the concentration of reactants and drive the reaction to produce more ester, effectively increasing the yield.
- D. Dilute sulfuric acid: This acts as a catalyst but does not directly increase the yield.
Correct Answer:
Therefore, the answer is C. More alkanol.
