Melting point of crude acetaminophen and purified acetaminophen are in similar range it indicates that the fine product is pure.
why is the melting point of crude acetaminophen similar to the purified acetaminophen?
Synthesis of Acetaminophen Postlab Questions During the crystallization of acetaminophen, why was the mixture cooled in an ice bath? 1. In the reaction between p-aminophenol and acetic anhydride to form acetaminophen, 0.450 mL of water was added. What was the purpose of the water? 2. Why should you use a minimum amount of water to rinse the conical vial while transferring the purified acetaminophen to the Hirsch funnel? 3. If 0.130 g of p-aminophenol is allowed to react with excess...
A student was trying to prepare acetaminophen in the laboratory. She found a melting point range of 169-173. The melting of acetaminophen is reported to be 168-172c. How could the student have verified that the produce is acetaminophen?
Compound X has just been successfully synthesized. Crystals of the crude product had a melting point range of 120 - 130 °C. After recrystalization, the new melting point range was 124.5 - 125.5 °C. Which sample was more pure, the crude product or recrystallized product? Why?
Can you please help calculate the theoretical and percent
yield along with the work, thank you!
Mass of p-aminophenol: 1.50 Mass of crude acetaminophen: 2.36 Mass of purified acetaminophen: 1.02 Theoretical Yield of Acetaminophen: Percent Yield of Acetaminophen: g (show work in space provided below) % ( show work in space provided below) Melting point of purified Acetaminophen 170.2 ns

What are the melting point ranges of crude para-chlorobenzyl alcohol (product) in the crossed-cannizzaro reaction of para-chlorobenzaldehyde with formaldehyde. What do the melting point ranges mean and what is the literature melting point?
Decide which element probably has a melting point most and least similar to the melting point of magnesium. Argon Thallium Strontium Lead
How to determine melting point depression (when measuring from the midpoint of melting point ranges). For example what would be the melting point depression of a component such as benzoic acid with a crude melting point range of (108-124) and a final melting point range of (96-108).
3. The crude product is purified by addition of NaOH to solubilize it filtration to remove impurities, and then the product is reprecipitated by addition of HCl. Explain the chemistry of the base and acid addition,
help with melting point and pure product. thank you Bromination of Stilbene lab would my product be pure and why based on the following data Melting point Crude: 236.4 - 240.2 ℃ Product 238.7-239.9 ℃ Lit melting point: 235-241℃
