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...
