Synthesis of crude product.
1. Combine reagents (following either step A or B, depending on the
benzaldehyde assigned to
you). It is best not to use a brand-new conical vial right out
of the package, as the surface is not rough enough to help induce
precipitation.
A. In a 5-mL conical vial, combine 0.15 g of 3-nitrobenzaldehyde
(151.121 g/mol), 0.12 mL
of acetophenone (120.151 g/mol; d = 1.03 g/mL), and 0.80 mL of
95% ethanol.
