Jornd Experiment 7- Synthesis and Reactivity of tert-Butyl Chloride Via an SN1 Reaction Introduction/Background: Alkyl halides are compounds in which a halogen atom replaces a hydrogen atom of an alkane. Alkyl halides are classified as primary‚ secondary or tertiary depending on the number of alkyl substituents directly attached to the carbon attached to the halogen atom. The purpose of this lab was to properly prepare t-butyl chloride from t-butyl-alcohol in a concentrated hydrochloric acid.

Introduction: During this lab‚ we found the excess reactant and limiting reactant between Aluminum and Copper (ll) Chloride. Using stoichiometry‚ we were able to make predictions. Through the reaction 2Al + 2CuCl₂ → 3Cu + 2AlCl₃ we carried out this experiment and determined that the limiting reactant was CuCl₂ and that the aluminum was in excess. We also determined the percentage yield of copper. Purpose: The purpose of this experiment was to determine the limiting reactant and percentage yield

Week 2 Lab |Step 1: First Year Costs | | Question 1: What would the first-year costs be to AML if it purchased the 10 used 20-foot containers? How long would it take to recoup the investment‚ assuming that the mushroom traffic continued? Based on 120 container shipments per year with 10% loads return or 12 containers‚ this would generate revenues equal to the associated cost.
