Hydrogen Bonding: One Interaction, Many Consequences
Chemical Bonding · Class 11 Hydrogen Bonding: One Interaction, Many Consequences Why water boils at 100°C, why ice floats, why ortho-nitrophenol is more volatile than the para isomer — all the same explanation. Class 11 & 12 · Chemical Bonding · Concept The short answer: A hydrogen bond needs hydrogen attached to nitrogen, oxygen or fluorine, and a lone pair on another such atom to accept it. It is about ten times stronger than an ordinary dipole interaction and roughly a tenth the strength of a covalent bond. Almost every anomaly in Class 11 and 12 physical property data traces…
