Explain your answer. flask. PLEASE HELP!! I do not know how to find theoretical yield or However, the reason why ring formation does not follow this trend is because of another factor called the proximity effect. Show more. Mole of Acetaminophen: (1.31g / 151.16 g/ mol) = 0.0086 mol, Mole of Ethyl iodide: (1.81g / 155.97 g/ mol) = 0.0116 mol, Phenacetin molecular weight: 179.22 g/mol, Theoretical Yield: (0.0086 mol x 179.22 g/mol) = 1.54 g, % Yield: (0.613 g / 1.54 g) x 100% = 39.81%.

The Williamson Ether synthesis is the easiest, and perhaps the fastest, way to create ethers. The proximity effect states that the nucleophilic part of the carbon chain is so close to the electrophilic carbon that a small amount of ring strain is evident in the ground state of the molecule. The relative speeds of ring formation are influenced by both enthalpic and entropic contributions. Insightful background material.
