Question

In the synthesis of isoamyl acetate, what part of the distillate should be collected (between which temperatures)?

a) Below the boiling point of isoamyl acetate
b) Between the boiling points of isoamyl alcohol and acetic acid
c) Between the boiling points of isoamyl acetate and isoamyl alcohol
d) Above the boiling point of isoamyl acetate

Answer 1

In the synthesis of isoamyl acetate, the appropriate distillate to collect is between the boiling points of isoamyl acetate and isoamyl alcohol, to ensure purity of the desired ester.

Step-by-step explanation:

In the synthesis of isoamyl acetate, the part of the distillate that should be collected is c) Between the boiling points of isoamyl acetate and isoamyl alcohol. This ensures that the desired ester is collected without significant contamination from unreacted alcohol or other components with lower boiling points. When performing a distillation, it is important to know the boiling points of the involved substances so you can collect the distilled compound at the correct temperature. Also, understanding the properties of the compounds such as solubility plays a crucial role in the purification process.
