This occurs when two functionalgroups of a molecule can form hydrogen bonds with each other. In order for this to happen, both a hydrogen donoran acceptor must be present within one molecule, and they must be within close proximity of each other in themolecule. For example, intramolecular ...
Hydrogen bonding can only happen in molecules that have a permanent dipole (as water does) and that also contain the highly electronegative elements fluorine, oxygen, or nitrogen.Not all molecules are sticky. Those which cannot form hydrogen bonds we can think of as slippery. The scientific name...
First, tsunamis are what happen after underwater earthquakes, quakes close enough to the ocean floor, or quakes that send landslides into the ocean — all displacing a great deal of water. The quake must also fracture the Earth's surface but at no more than 70 kilometers deep, and it mus...
What types of bonds exist between the atoms in a molecule of H2O? Which type of bond occur between bases in a DNA base-pair? a. covalent bonds b. ionic bonds c. hydrogen bonds What will happen if some of the hydrogen bonding capable groups such as C=O, O-H or N-H do not form...
“It’s an electrochemical transaction, the reaction that produces an electron,” explains Ben Nyland, president and CEO of fuel cell maker Loop Energy. “A fuel cell basically makes that electrochemical reaction happen, and captures the electrons that result from it and feeds those out in the ...
The narrow pore allows only one water molecule to pass, thus generating the single-file water wire with three remarkable H-bonds between water and channel inner surface, HH2O–--Ntriazole, HH2O–--O(-O-) (Fig. 12d). The authors have revealed that different positive, negative and ...
Although hydrogen bonding is commonly described as a form of dipole-dipole attraction, it is now clear that it involves a certain measure of electron-sharing (between the external non-bonding electrons and the hydrogen) as well, so these bonds possess some covalent character. Hydrogen bonds are ...
The majority of mutual orientation angles between molecules lie in the interval [0°; 20°]. More than 85% of the molecular pairs in each instantaneous configuration form H-bonds and the H-bond network includes all water molecules in the temperature range 233–293 K. The number of H-...

Extracting hydrogen by breaking the bonds between hydrogen and carbon content is one of the most popular methods of hydrogen production [16]. This substance can be extracted from biomass [45], coal [46], gasoline, oil (heavy and light), methanol and methane [12]....
