Which substance is an example of a nonpolar compound?

A.sugar
B.food coloring
C.water*
D.vegetable oil

The correct answer is D. vegetable oil. Vegetable oil is an example of a nonpolar compound because it consists mainly of long hydrocarbon chains, which have predominantly nonpolar covalent bonds.

To determine which substance is an example of a nonpolar compound, we need to understand the concept of polarity. Polarity refers to the distribution of electrical charge within a molecule.

A nonpolar compound is one in which the electron distribution is equal or almost equal across the molecule, resulting in no significant positive or negative regions. Nonpolar compounds are generally hydrophobic (not soluble in water) and usually dissolve in nonpolar solvents.

Now, let's analyze each of the given substances:

A. Sugar: Sugar is a polar compound. It consists of molecules with various hydroxyl (OH) functional groups. These functional groups make sugar water-soluble and capable of forming hydrogen bonds with water molecules.

B. Food Coloring: Food coloring can vary, but many food coloring molecules are polar. They are often water-soluble and have polar functional groups in their structure.

C. Water: Water is a polar compound. Its molecule has a bent shape, with the oxygen atom being more electronegative than the hydrogen atoms. As a result, the oxygen atom pulls the shared electrons closer to itself, creating a partial negative charge (δ-) on the oxygen and partial positive charges (δ+) on the hydrogen atoms.

D. Vegetable Oil: Vegetable oil is an example of a nonpolar compound. It consists mainly of triglycerides, which have a long nonpolar hydrocarbon chain called a fatty acid. Fatty acids are hydrophobic, insoluble in water, and dissolve well in nonpolar solvents.

Based on this analysis, the correct answer is D. Vegetable oil, which is an example of a nonpolar compound.
