Today, they're found in many pharmaceuticals. What is the IUPAC name for the compound shown below? A. (4E)-4-Methylhex-2-en-4-yne B. (4Z)-4-Methylpent-4-yn-2-ene C. (4E)-3-Methylhept-1-yn-4-ene D. (4Z)-3-Methylhex-4-en-1-yne}Answer: B The acid catalyst has the structure of a detergent, and in water, this molecule will form a micelle with a hydrophobic interior (long-chain hydrocarbons pointed inward). This interior environment is conducive for the insoluble (hydrophobic) acid and alcohol molecules, with water remaining on the outside of the micelle {Ans: A researcher uses the molecule below as an acid catalyst to enable the a reaction between a carboxylic acid and an alcohol.
