Question

Reaction Workup and Purification For the reaction depicted below.drowa flowchart for the isolation of the other product. Then explain why recrystallization would or would not be a good technique to put the este product this reaction. Assume the yield for this reaction is 92. You wil l need the first lecture on 10/7 to complete this explanation. You can at least complete the flow charts before this lecture) Follow up: What the yield was 53%? Hints. Remember that recrystallation would happen after the workplextraction. Think about what the yield could mean in terms of the product to reactant ratio at the end of the reaction DMF- 1 d -0.044 gml barl K.CO, HCO DE se je SUME neutral BP = 199 °C na ACA MP - 64 °C MP - 97 °C CA organic

Answer 1

Recrystallization is a good purification technique if the obtained product is a solid compound.

Whereas if the obtained product is a liquid and it contains other organic impurities having significantly differing retention factor (R_f) values, then column chromatography is the best purification technique.

If the obtained product is a liquid and it is highly viscous, then distillation is the best purification technique.

Now, coming to the reaction of benzyl iodide with 3,5-dimethylphenol to form the ether product shown in the reaction, distillation is the best purification technique.

So, you may obtain fewer yields such as 53% or so..
