The organic compounds that have a boiling point higher than water and which vaporize when exposed to temperatures above the room temperature, are called semi-volatile compounds. Volatile organic compounds. Volatile Organic Compounds. Chemical Substance. Volatile organic compound (VOC) are organic chemicals that have a high vapour pressure at room temperature.High vapor pressure correlates with a low boiling points, which relates to numbers of the sample's molecules in the surrounding air, a trait known as volatility.. VOC's are responsible for the odor, scents, and perfumes as well as pollutants. 3.
