What is the name of this compound 3HC-CH2-CH2-CH2-CH2-CH2- NH2?arrow_forwardEster 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…arrow_forwardArrange the following amines in increasing boiling point.
