Q1. 3-chloro-3,7-dimethyloctane undergoes a reaction in KOH/EtOH, H20 and produces products. Using one of the products, write the equations for the chemical reactions that will be used to establish alkene functional groups are present in your product. Do these reactions provide any information on the purity of alkene in your product?
Q2. Your reaction mixture is dissolved in ethanol and water. What is the temperature at which you expect that a simple mixture of ethanol and water will reach at the time that boiling (and thus reflex) starts? Does the presence of dissolved salts (NaOH) affect the temperature at which boiling of a solvent will be observed? In what way?
