Verified step by step guidance

Understand the basic structure of hydrocarbons: Hydrocarbons are organic compounds consisting entirely of hydrogen and carbon atoms. Their structure is typically a chain or ring of carbon atoms with hydrogen atoms attached.

Identify the properties of hydrocarbons: Hydrocarbons are generally hydrophobic, meaning they do not mix well with water. This is due to their nonpolar nature, as the carbon-hydrogen bonds do not create a significant charge difference.

Recognize the energy storage capability: Hydrocarbons are a good source of stored energy because the carbon-hydrogen bonds contain high energy. When these bonds are broken, energy is released, which is why hydrocarbons are used as fuels.

Differentiate between polar and nonpolar: Hydrocarbons are nonpolar because they lack a significant difference in electronegativity between the carbon and hydrogen atoms, resulting in an even distribution of electrical charge.

Evaluate the given options: Based on the properties discussed, the correct answer is the option that describes hydrocarbons as hydrophobic, nonpolar, and a good source of stored energy.
