Did you know?
Did you know that for the organic compound "Vanillin" (C8H8O3) the standard state refers to the physical state of the compound at a defined temperature and pressure? In the case of Vanillin, the standard state is typically solid at room temperature and normal atmospheric pressure since it is commonly found and used in its solid form, such as in vanilla extract.
Another interesting fact is that the vapor pressure of Vanillin is considered relatively low. Vapor pressure refers to the tendency of a substance to evaporate or vaporize at a given temperature. Vanillin has a relatively low vapor pressure due to its strong intermolecular forces, which hold the molecules together and limit their ability to escape into the gas phase. This is why the aroma of vanilla can linger in the air for a long time.
Furthermore, the melting and boiling points of Vanillin are relatively high. The melting point of Vanillin is around 80-81°C, while the boiling point is approximately 285-290°C. These high temperatures are indicative of the strong intermolecular forces present in Vanillin, which require a significant amount of energy to break and convert the compound from solid to liquid or liquid to gas.
