Which of the following substances is an example of a volatile alcohol?

Volatile alcohols are substances that have a relatively low boiling point and can easily evaporate at room temperature. Rubbing alcohol, which is primarily composed of isopropyl alcohol or ethanol, exemplifies this property. It is used for disinfecting and cleaning due to its quick evaporation rate and is commonly recognized for its strong odor, which is typical of volatile compounds.

Water, glycerin, and olive oil do not exhibit the same volatility characteristics as rubbing alcohol. Water, while it can evaporate, is not categorized as an alcohol. Glycerin, which is a thicker and more viscous substance, has a much higher boiling point and does not evaporate quickly, making it less volatile. Olive oil is a fatty substance and, like glycerin, does not have the properties associated with volatile alcohols. Thus, the defining characteristics of volatility lead to rubbing alcohol being the only suitable example in this context.
