Can you explain how to find what is the theoretical yield, and
the desired percent yield of ethyl 4-nitrobenzoate?
1. Synthesis of ethyl 4-nitrobenzoate a) In a 50-ml round-bottom flask, weigh out 4-nitrobenzoic acid (0.85 g, 0.005 mol). Add to this 8 ml of absolute ethanol. Add boiling stones, and then bring this solution to the Lab Technologist. WATER OUT b) The Lab Technologist will deliver 1.2 ml of concentrated sulfuric acid to the mixture from the automatic pipette. [CAUTION,...

1. Why is it important to chill the water that will be used for rinsing/washing the precipitate 2. In the synthesis of salicylic acid reaction, percent yield 75% - 85% are not uncommon. ( if the percent yiels are much higher it is likely that your product was still wet when you weighed it.) Explain why very high percent yiled (>95%) are not expected in this lab. 3.Compare the melting point ranges of the pure salicylic acid sample and your...

In a 125-mL Erlenmeyer flask containing a magnetic stirring bar, mix 0.05 md benzaldehyde with the theoretical quantity of acetone, and add one-half the ture to a solution of 5 g of sodium hydroxide dissolved in 50 mL of water and 40 mL of ethanol at room temperature (<25°C). After 15 minutes of stirring ada remainder of the aldehyde-ketone mixture and rinse the container with a little ethanol to...

Please help with question 3. Thank you!
Disposal of waste: When necessary, all organic waste must be disposed into the organic waste container, all aqueous waste to the aqueous waste container and all solid waste to the solid waste container. Nothing is disposed in the sink or trash can. Synthesis of acetanilide In a dry small conical vial, dissolve 300 mg (or 30 drops) of freshly distilled aniline in 1.0 mL of 1.0 M hydrochloric acid. Swirl the mixture to...

Multistep Synthesis: Synthesis of Amine (Organic Chemistry
Lab)
Question
1. Explain each step of reaction mechanism. (How does it
work?)
2. Discuss reason for reaction sequence. (Why must one reaction
occur before another?)
3. Explain how IR supports the major product.
Experiment Procedure
Imine Formation:
Weigh a 20 mL beaker and then add 380 mg of ortho-vanillin and
268 mg of para-toluidine. Care should be taken to add equivalent
molar amounts of the two reactants.
Observe the mixture and record...
