Why are ethers used as inhalation in general anesthetics? Describe why we do no use diethyl ether as a general inhalation anesthetics anymore? What are we using today as general inhalation anesthetics? Are there draw backs to modern day inhalation as the anesthetics?

Avobenzone and dioxybenzone are two commercial sunscreens. Using the principles of solubility, predict which sunscreen is more readily washed off when an individual goes swimming. Explain your choice.

Why does old aspirin smell like vinegar?

It has been known for a very long time that lemon juice can mask the "fishy" smell of cooked fish. The "fishy" smell is often due to the presence of amines, such as putrescine, shown below. Lemon juice contains up to 5% citric acid, also shown below. Based on your knowledge amine chemistry and carboxylic acid chemistry, what could be occurring when lemon juice is put on the cooked fish? H₂N NH₂ putrescine, a smelly fish compound HO O O OH 0 OH OH citric acid, a major componant in lemon juice The citric acid undergoes an E2 reaction with the putrescine. The citric acid protonates the putrescine. The citric aicd undergoes and Sn2 reactions with putrescine. The citric acid oxidizes the putrescine. The citric acid hybridizes the putrescine.

1. Write the balanced chemical equation for the synthesis of acetylsalicylic acid and methyl salicylate. 2. Enumerate some uses of soap and detergent at home. What are the conditions that favors the use of soap over detergents?

Ester compounds often have a sweet, pleasant odor. Many characteristic fruit scents are largely due to the natural presence of one or more ester compounds. As such, artificial scents for foods are often composed of complex mixtures of various esters. The exact identity and ratio of ingredients that compose a particular scent are closely guarded secrets in the food and fragrance industry. Suppose that you are a chemist working for a company that i creating a new line of air fresheners. The company is considering three scents: apple, pear, and pineapple. The project manager has asked you to prepare the ester compounds that are largely responsible for these scents. The structural formulas for these ester compounds are shown here: Alcohols for Air Freshener Project Molar mass Density Cost, per (g/mL) Reagent (g/mol) 1.00 L methanol 32.04 0.79 $46.20 ethanol 46.07 0.79 $112.00 1-propanol 60.10 0.80 $72.70 1-butanol 74.12 0.81 $72.60 Use the structural formulas of the alcohols and…

acetylsalicylic acid vs salicylic acid? What is the main chemical difference? Why can acetylsalicylic acid pass through the stomach without harm while salicylic acid can cause harm to the stomach????

Indole and pyridine rings are found in alkaloids.a. Sketch each ring.b. Name one compound containing each of the ring structures and indicate its use.

1) To identify which contains more acid vinegar or lemon juice neutralization with sodium hydroxide can be used. Explain how. 2) The long filaments making up the thread of woven synthetic fabrics are likely polyesters. Describe the special characteristic that the alcohol and carboxylic acid must have so that they can react with each other to produce such long filaments.
