I was reading the wiki on hydrogen bonds... They had to go and mention Thermonuclear - which happens to be my favorite word, I also have a soft spot for nuclear fusion.... Fission is for old people! I will, at some point today, look at YouTube videos of The Bikini Islands tests. Hydrogen bond For hydrogen bomb, see Thermonuclear weapon. Model of hydrogen bonds (1) between molecules of water A hydrogen bond is the electromagnetic attractive interaction between polar molecules, in which hydrogen (H) is bound to a highly electronegative atom, such as nitrogen (N), oxygen (O) or fluorine (F). The name hydrogen bond is something of a misnomer, as it is not a true bond but a particularly strong dipole-dipole attraction, and should not be confused with a covalent bond. These hydrogen-bond attractions can occur between molecules (intermolecular) or within different parts of a single molecule (intramolecular).[1] The hydrogen bond (5 to 30 kJ/mole) is stronger than a van der Waals interaction, but weaker than covalent or ionic bonds. This type of bond can occur in inorganic molecules such as water and in organic molecules like DNA and proteins. Intermolecular hydrogen bonding is responsible for the high boiling point of water (100 °C) compared to the other group 16 hydrides that have no hydrogen bonds. Intramolecular hydrogen bonding is partly responsible for the secondary and tertiary structures of proteins and nucleic acids. It also plays an important role in the structure of polymers, both synthetic and natural. In 2011 an IUPAC Task Group recommended a modern evidence-based definition of hydrogen bonding. The new definition was published in the IUPAC journal Pure and Applied Chemistry.[2] This detailed technical report provides the rationale behind the new definition.[3]
