CHEM 3401 PreLaboratory Assignment, Elimination Reactions of Alkyl Halides, day 2 Due at the beginning of the lab period. Reading Assignment from Zubrick, 9th ed.: Reflux, pp. 201-202; Elimination Reactions of Alkyl Halides Experiment, GSU Laboratory Manual 1. What purpose does the water in the Hempel column/condenser serve in the reflux setup? The purpose of the water in the Hemper column] ondenser is too cool vapors before they leave the system, which maintains volume and induces reaction 2. You are...
Alkyl Halides: Elimination reaction with (2R,3R)-2-chloro-3-methylpentane Draw the product formed when (2R,3R)-2-chloro-3-methylpentane under-goes an elimination reaction with NaOCH3. Alkyl Halides: Elimination reaction with 3-chloro-3-ethyl-2,2-dimethylpentane. Draw the structure of the product that is formed when 3-chloro-3-ethyl-2,2-dimethylpentane undergoes an elimination reaction with NaOCH3. Indicate the stereochemistry of the product. Identify the three products formed when 2-bromo-2-methylpropane is dissolved in a mixture of 80% ethanol and 20% water.
