Question

In today's experiment, you will be recrystallizing a "dirty" sample of benzoin. Choose the statement that best explains how you will determine your sample?

a. The yield of my product is high
b. The appearance of the product matches the literature description
c. The melting point range should be less than 3 C
d. The melting point range matches the literature values.

Answer 1

Answer:The melting point range matches the literature values.

Step-by-step explanation:

The essence of recrystallization is obtaining the sample in its purest form. This purest form must have the exact properties of the compound as reported in literature. The melting point is part of the means of identifying a pure compound. A pure compound must have a sharp melting point which corresponds with literature reports. Hence the melting point is quite a good means for determining a sample.
