Please Calculate the theoretical yield and the percent yield of this aldol reaction.
Unknown ketone: cyclohexanone
Unknown aldehyde: p-Anisaldehyde
Actual yield: 0.067
Our aldol mixture was our unknown ketone (0.002 mol) with 4.0 mL of 95% ethanol in a 25 mL Erlenmeyer flask. And we added our unknown aldehyde (0.008 mol) and 3.0 mL of 1 M NaOH.

In a 125-mL Erlenmeyer flask containing a magnetic stirring bar, mix 0.05 md benzaldehyde with the theoretical quantity of acetone, and add one-half the ture to a solution of 5 g of sodium hydroxide dissolved in 50 mL of water and 40 mL of ethanol at room temperature (<25°C). After 15 minutes of stirring ada remainder of the aldehyde-ketone mixture and rinse the container with a little ethanol to...

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...

Experimental Outline In its simplest form, the aldol condensation is a self-addition involving two molecules of the same aldehyde or ketone, in the presence of a base, and results in the formation of a new carbon-carbon bond joining the carbonyl carbon of one molecule to the a-position of the second. In many cases - if the reaction conditions aren't sufficiently mild - the initially formed aldol product reacts further in an elimination reaction to give what is...
