Problem- What is the mol% of Pd used in this reaction? (ex: 5% mol% catalyst means that the reaction uses 5% as much catalyst as limiting reactant)
I dissolved .179 grams of 1-methyl-4-bromobenzene to 5 mL ethanol. I added .155 g 4-methoxyphenylboronic acid. I rinsed the vial with 2 mL ethanol and added the washings to the reaction mixture, followed by Pd solution (200 microliters, 1.0 mg/mol Pd in water). I stirred for 1 minute and then added 1 mL of KOH.
State your answer by means of two significant figures.
