why is it easier to remove excess acetic acid from the products than excess isopentyl alcohol?
from the products of what? Did you perform an experiment in class and this is one of the lab questions? If so you will need to explain what you did in some detail; otherwise, we're in the dark.
We did an experiment with acetic acid and isopentyl alcohol to form isopentyl acetate, or banana oil.
How did you remove the excess acetic acid?
We discarded the excess acetic acid after adding sodium bicarbonate...

To understand why it is easier to remove excess acetic acid from the products than excess isopentyl alcohol in the formation of isopentyl acetate (banana oil), we need to consider their different properties.
First, let's analyze the reaction that takes place during the formation of isopentyl acetate:
Acetic acid + Isopentyl Alcohol → Isopentyl Acetate + Water
During this reaction, the acetic acid and isopentyl alcohol react to form isopentyl acetate. However, it is often the case that not all the starting materials are completely consumed, and there may be excess reactants left over after the reaction has taken place.
In this particular case, excess acetic acid is easier to remove from the products compared to excess isopentyl alcohol due to a few reasons:
1. Solubility: Acetic acid is highly soluble in water, which means that it can easily dissolve in an aqueous solution. This solubility allows for efficient separation from the organic phase that contains the isopentyl acetate. By adding a substance like sodium bicarbonate, which is basic, the excess acetic acid can be converted into its sodium salt (sodium acetate) during an acid-base reaction. Sodium acetate is water-soluble and can be easily separated from the organic phase.
2. Volatility: Acetic acid has a lower boiling point (around 118 °C) compared to isopentyl alcohol (around 130 °C). This difference in boiling points makes it easier to remove excess acetic acid through evaporation. By applying heat, the acetic acid can be vaporized and collected, leaving behind the desired isopentyl acetate.
On the other hand, removing excess isopentyl alcohol can be more challenging because it is not as soluble in water as acetic acid. It would require additional steps such as distillation or purification techniques, which may involve more complex processes and equipment.
In summary, the higher solubility of acetic acid in water and its lower boiling point make it easier to remove excess acetic acid from the products, compared to excess isopentyl alcohol.
