Without a complete pre-lab assignment, you will not be allowed to perform the experiment, and will receive a zero for the lab.) …..max score = 20 pts. 1. Objective (In the provided space, write a brief purpose of the experiment, addressing all of the following points: ) Name the class of reactants combined during the synthesis and the class of product formed. What is the purification technique used in this experiment? What analytical technique will be used during the experiment? What type of spectral analysis will be used to characterize the reactant and products? 2. Chemical Equation (In the provided space, draw the chemical equation for the synthesis of 2-methyl-2-hexanol using actual chemical structures.) 3.

Pre-Lab Question (Answer the following question prior to lab.) a. In the lab, Grignard reactions can be slow to initiate because of the magnesium metal turnings. This is because: i. The magnesium is flammable. ii. The magnesium is coiled too tightly. iii. The magnesium reacts with air to form a magnesium oxide coating. iv. The magnesium metal reacts with water.
