Determine the mmol of both starting materials (factoring in that
formic acid is not pure, but rather 88% weight/volume, or 88g/100
ml), showing your work. Determine the limiting reagent in this
synthesis. Lastly, calculate the theoretical yield of benzimidazole
that you could expect to form.
Experimental procedure
Reaction
1. Into a 4ml conical vial (microscale!), add o-phenylenediamine
(108 mg = 0.108 g) and formic acid (88% aqueous solution
[weight/volume](0.064 mL) using a 20-200 µL micropipette (aka
“biological pipette” or “micro...
