what is the theoretical yield of anisalacetophenone and
dibenzalacetone formed? thank you.
The Aldol Condensation Precautions: Acetone, ethanol and acetophenone are flammable; work in a fume hood. Sodium hydroxide is a strong base and can cause severe skin burns and eye damage. Safety goggles are required. Gloves are recommended. Purpose To carry out two Aldol condensation reactions in which no heat is needed to obtain the condensation product. The two reactions differ in the number of enolizable protons at the...

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

help with limiting reagents and percent yield needed
the
reactions are the bromination of cis-stilbene and trans-stilbene.
The reagents and the moles of each reagent are in my data, as is
the moles of the products formed. The volume and mass of the
reagents are given as well. I need to know how to find the percent
yield and what the limiting reagents are for both the trans and cis
stilbene brominations. The information is there.
