Transcribed Image Text:**Chemical Reaction Exercise**
In this exercise, you will analyze a chemical reaction between an aldehyde and a ketone in the presence of sodium hydroxide (NaOH) and ethanol. Review the provided data and answer the following questions.
**Reaction Scheme:**
- Aldehyde Structure: Molecular Weight (MW) = 150.13 g/mol, Density = 1.34 g/mL, 1.02 g used
- Ketone Structure: Molecular Weight (MW) = 100.16 g/mol, Density = 0.80 g/mL, 0.69 g used
- Reaction Conditions: 0.75 mL of 33% NaOH, 7 mL of ethanol
**Questions:**
a) What is the molecular weight of the product?
- ________________
b) What number of moles of aldehyde were used?
- ________________
c) What number of moles of ketone were used?
- ________________
d) What was the limiting reagent?
- ________________
e) If 0.135 g of product was isolated, what was the percentage yield of the product?
- ________________
f) What is the name of this reaction?
- ________________
**Instructions:**
1. Calculate the number of moles for both the aldehyde and ketone using the given mass and molecular weight.
2. Determine the limiting reagent in the reaction.
3. Calculate the theoretical yield and compare it with the actual yield to find the percentage yield.
4. Identify the reaction type based on the reagents and conditions provided.
Ensure to show all calculations and reasoning used to arrive at your answers.
