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.

What is the limiting reagent in this experiment? Acetophenone or
aqueous bleach?
1. Add about 1.0 g (measured accurately) of acetophenone to 40 mL of the bleach solution (5% NaCl in water - this reactant should be included in your table of reagents!) in a 100 mL round bottom flask equipped with a magnetic stirrer. Clamp the flask in the fume hood above a stir plate. 2. After the initial reaction has subsided, boil the reaction mixture gently for 5...

NUCLEOPHILIC DISPLACEMENT- FORMATION OF AN ETHER BY AN SN2 REACTION Bond formation by use of an SN2 reaction is very important for organic and biological synthesis. Many new bonds formed make use of this versatile reaction pathway. In this reaction, one partner is the nucleophile and the other partner is the electrophile. The electrophile will have a leaving group that will be lost in the reaction. In the SN2...

In this Diels-Alder reaction, what is the limiting reagent for
this reaction? Please show work
In this experiment, a Diels-Alder reaction will be performed to generate 4-cyclohexene- 1,2-dicarboxylic anhydride. The reaction occurs when 1,3-butadiene is combined with maleic anhydride and heated as shown below. Once the product has been isolated, the IR spectrum, melting point, and experimental yield can be determined. 5.- I111NI O Due to the inherent difficulties with the handling of gaseous 1,3-butadiene, it will be generated in...

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...
