lab G: (e)- stilbene, pyridinium tribromide, meso-stilbene dibromide, potassium hydroxide, triethylene glycol, diphenylacetylene, ethanol

Mole Table Drawn immediately beneath the Overall Reaction, the Mole Table is used to calcu late the theoretical yield of your product using stoich iometry. All calculations are to be shown in the "Calculations" section. Each column refers to the structure drawn above it. Please cite the source of Mole Table information stated in the Mole Table - refer to the example below for format. As well, CLEARLY label the limiting reactant of the reaction. Remember: Only liquids have densities of interest; do not report solid densities. Solution molarities should be recorded. Use 'N/A' for information that is not applicable. For example, the # of solvent moles used is rarely part of the stoichiometry of a reaction -so you would write 'N/A' in the solvent's "# of Moles" box in the Table. Mole Ratio divide all reagents/products by the lowest # of moles. All Mole Ratios should be "1" or greater. This shows that you, indeed, chose the correct limiting reactant
