Think about what happens when you combine oil (such as olive oil) and water. What happens? Is oil polar or nonpolar?
When you combine oil (such as olive oil) and water, they do not mix or dissolve in each other. Instead, the oil forms droplets that float on top of the water, creating a distinct layer. This phenomenon is due to the difference in polarity between oil and water molecules.
Oil, including olive oil, is nonpolar. It consists of long hydrocarbon chains that have mostly carbon and hydrogen atoms. These hydrocarbon chains do not have an electrical charge and do not readily interact with polar substances like water. Thus, oil is classified as a nonpolar substance.
a
The oil dissolves. Oil is nonpolar.
b
The oil dissolves. Oil is polar.
c
They remain separate. Oil is nonpolar.
d
They remain separate. Oil is polar.
