🗺️ The Molecular Interaction
1. Ortho-nitrophenol: The  and  groups are right next to each other. They form an intramolecular Hydrogen bond (within the molecule). This creates a "shielded" molecule that doesn't like to stick to its neighbors. It has a lower boiling point and is steam volatile.
2. Par
