Boiling point in organic compounds

WebThe boiling point of organic compounds depends on the level of attractions between neighbouring molecules. If those attractions are high the boiling point will be high. If the attractions are weak the boiling point will be weak. These attractive forces are due to the collection of intermolecular forces within a sample. In the following lab you ... WebNov 12, 2024 · The European Union (EU) thus defines VOCs as any organic compound with an initial boiling point that is less than or equal to 250°C at an atmospheric pressure of 101.3 kPa. Distinctions are drawn between VOCs, very volatile organic compounds (VVOCs), and semi-volatile organic compounds (SVOCs).
