4. Multiple Choice Place your answer in the space provided. (2 pts. each; 12 pts. total) Which is NOT true of the aldol condensation? A. It accomplishes the formation of a new carbon-carbon bond B. The enolate is favored at equilibrium (assume NaOH as the base) C. The key step is the mechanism is attack of the enolate ion on a carbonyl carbon atom D. Dehydration of the aldol product is often observed and is irreversible. _Which sets of hydrogen...

1151 VCL 11-8: Claisen Condensation -1 For this assignment, the target compound that you should synthesize is methyl acetoacetate. This is another carbonyl addition variation. Examine the product and determine which ester is the nucleophile and which is the electrophile. Keep in mind the mechanism and that you need to acidify the intermediate in order to isolate a neutral product. Synthesis Procedures 1. Start Virtual ChemLab and select Claisen Condensation-I from the list of assignments in the electronic workbook. After...

Problem 2 (15 pts) A spherical container containing radioactive waste is thrown into the ocean waters maintained at 300 half of the container is made of stainless steel with a thermal conductivity of 15.1 W/mK. The convection coefficient has the same value of 555 W/m2 K with both lid and bottom. The inner radius of the co the container is 600 K (the same for the lid and may be assumed to have an infinite contact resistance. Assume that the...
