Which of the following best describes alcohols?

The choice that best describes alcohols is the statement that alcohols are colorless volatile liquids that will mix with water. Alcohols, such as ethanol and methanol, are organic compounds that contain one or more hydroxyl (-OH) functional groups.

The characteristic of being colorless indicates that many common alcohols appear clear and transparent, which is true for substances like ethanol. The term "volatile" refers to their ability to easily evaporate at room temperature, highlighting their tendency to transition from liquid to gas. This volatility is an important property of alcohols, impacting their use in various applications, such as solvents and fuels.

Additionally, alcohols are known for their solubility in water, primarily due to the hydrogen bonding capability of the hydroxyl group. This property allows alcohols to mix well with water, setting them apart from many other organic compounds that do not dissolve effectively in water.

These features make the description provided in this choice accurate, as it encapsulates the essential characteristics of alcohols effectively.
