Which of the following is a feature of rubbing alcohol?

• A. Low toxicity
• B. High vapor pressure
• C. High viscosity
• D. Non-flammable

Answer: (B)

Rubbing alcohol, commonly known as isopropyl alcohol or ethanol, is characterized by a high vapor pressure. This property allows it to evaporate quickly at room temperature, which is why it is often used as a solvent and antiseptic. The high vapor pressure indicates that the molecules in the liquid state tend to escape into the vapor phase readily, contributing to its effectiveness in cleaning and disinfecting surfaces. While other properties like low toxicity can depend on concentration, and the flammability of alcohols may vary with different formulations, the key feature that stands out in this context is the high vapor pressure, making it efficient for its intended uses. Viscosity, which refers to the thickness or resistance to flow of a liquid, is generally low for rubbing alcohol, further highlighting the importance of its high vapor pressure characteristic.
