A student conducted a chromic acid oxidation of alcohol experiment on five different alcohols by reacting them with an acidic solution of potassium dichromate. The student individually reacted ethanol, 1-propanol, 2-propanol, 2-methoxyethanol, and ethylene glycol with the acidic solution to measure each compound's reaction rate constant. The student found that 1-propanol had the largest rate constant, ethanol had the second largest, followed by 2-propanol. 2-methocyethanol had the smallest k value. Explain why the reaction rate constant of 2-methoxyethanol was smaller than that of ethylene glycol.

A student conducted an experiment to determine what factors are important in the rate of reaction between potassium carbonate and hydrochloric acid. The student diluted 4.000 mL of 4.000 M K2CO3 to 150.0 mL, then combined that solution with 150.00 mL of 2.000 M HCl at an increased temperature of 50 °C. The student tabulated the amount of CO2 gas collected over time and recorded the results in the columns to the left. 1. Use a rearrangement of PV =...

13 SN1: Synthesis of tert-Butyl Chloride Alkyl halides can be prepared from their corresponding alcohols via an acid catalyzed substitution reaction. The mechanism of these acid catalyzed substitution reactions are labeled as Syl (substitution, nucleophilic, unimolecular) and S2 (substitution, nucleophilic, bimolecular). Tertiary alcohols follow the Snl route, primary alcohols follow the S2 route, and secondary alcohols can follow either path. Under acidic conditions, the mechanism (Figure 1) of the Sul reaction involves rapid protonation of the alcohol, followed by the...
