Interpretation Introduction

Interpretation:

The reason as to why the loss of mass is usually unsatisfactory to measure the rate of decay is to be predicted. The other method and its advantage are to be predicted.

Concept introduction:

The decay constant is the quantity that expresses the rate of decrease of a number of atoms of a radioactive element per second. Half-life is defined as the time required for the number of nuclides to reach half of the original value.

Kumada Coupling: 1. m-Diisobutylbenzene below could hypothetically be synthesized by Friedel-Crafts reaction. Write out the reaction with a mechanism and give two reasons why you would NOT get the desired product. Draw the reaction (NOT a mechanism) for a Kumada coupling to produce the molecule above from m-dichlorobenzene. Calculate the theoretical yield for the reaction in question 2 using 1.5 g of p-dichlorobenzene and 3.0 mL isobutyl bromide. What signals appeared/disappeared/shifted that indicate that you have your intended product and not starting material? What other impurities are present in your product and how do you know?
Wintergreen from Aspirin: 1. In isolating the salicylic acid, why is it important to press out as much of the water as possible? 2. Write the mechanism of the esterification reaction you did. 3. What characteristic absorption band changes would you expect in the IR spectrum on going from aspirin to salicyclic acid and then to methyl salicylate as you did in the experiment today? Give approximate wavenumbers associated with each functional group change. What signals appeared/disappeared/shifted that indicate that you have your intended product and not starting material? What other impurities are present in your product and how do you know?
Synthesis of ZybanⓇ: 1. Write a mechanism for the bromination of m-chloropropiophenone. Br₂ CH2Cl2 Cl Br 2. Give the expected m/z (to a round number) for the molecular ion from the product above (including isotopic peaks). 3. What signals appeared/disappeared/shifted that indicate that you have your intended product and not starting material? What other impurities are present in your product and how do you know?
