the product in a Coumarin synthesis lab is soluble in aqueous base. Why?

1.The base deprotonates α- to the carbonyl to form an enolate ion.

2.The base deprotonates α- to the phenol to form a phenylate anion.

3.The base deprotonates the phenol hydroxyl to form a phenoxide anion.

4.The product is water soluble.

Expert Solution

Answer: 3.The base deprotonates the phenol hydroxyl to form a phenoxide anion.

Reason: I have attached Dry lab page below for your kind consideration and hope the same product you synthesized, if not no worries - the phenol hydroxyl group is deprotonated in all types of products formed from Coumarin.

Mg(OH)2 is a sparingly soluble compound, in this case a base, with a solubility product, Ksp, of 5.61×10−11. It is used to control the pH and provide nutrients in the biological (microbial) treatment of municipal wastewater streams. Part A: Based on the given value of the Ksp, calculate the ratio of solubility of Mg(OH)2 dissolved in pure H2O to Mg(OH)2 dissolved in a 0.160 M NaOH solution. Part B: What is the pH change of a 0.300 M solution of...

Why is each of the three solids (acid, base, and neutral) soluble in diethyl ether? Examine the structure of each solid and explain what factors increase solubility in water vs. the organic solvent used. Identify the significant intermolecular forces affecting solubility. Please explain why two layers form when 3 M NaOH is added to the ether solution. What solvents do the two layers represent and which solvent forms the upper layer? 3 solids are Benzoic acid, 4-aminobenzoate, and 9-fluorenone. Thank...

Describe the steps in the synthesis and transport of a soluble, N-glycosylated glycoprotein from when is emerges from the ribosome during translation, until it is secreted at the cell surface. Be sure to include glycan synthesis and transfer to the protein. I have seen this question been posted earlier, but I was wondering if someone could "dumb" it down for me as I find the process quite confusing. Thank you in advance!
