Oxygen AdditionsNitrogen AdditionsThe temperature dependency of the phosphorescence properties of aromatic hydrocarbons (phenanthrene) in alcoholic glasses exhibits a number of phenomena that have not been previously described. Chief among these are the effects of added gases (O sub 2 , N sub 2 , C...
Here we employ a library of protic ionic liquids in an interfacial layer on platinum and gold to alter local proton activity, where the intrinsic oxygen-reduction reaction (ORR) activity is enhanced up to fivefold, exhibiting a volcano-shaped dependence on the pKa of the ionic liquid. The ...
Although hydrogen bonds form between hydrogen and any other electronegative atom, the bonds within water are the most ubiquitous (and some would argue, the most important). Hydrogen bonds form between neighboring water molecules when the hydrogen of one atom comes between the oxygen atoms of its o...
Water electrolysis relies on the application of an electric current through an anode and cathode inserted in the electrolyte to provide the required energy to break the hydrogen and oxygen bond. While the basis remains the same, different electrolysis methods including polymer electrolyte membrane electr...
The meaning of HYDROGEN BOND is an electrostatic attraction between a hydrogen atom in one polar molecule (as of water) and a small electronegative atom (as of oxygen, nitrogen, or fluorine) in usually another molecule of the same or a different polar su
(Chemistry) a weak chemical bond between an electronegative atom, such as fluorine, oxygen, or nitrogen, and a hydrogen atom bound to another electronegative atom. Hydrogen bonds are responsible for the properties of water and many biological molecules ...
1.2.4.3 Hydrogen bond Hydrogen bonding refers to a weak bond formation between a hydrogen atom attached to a strong electronegative atom and another atom of higher electronegativity. Hence, the hydrogen atom, which is connected to a highly electronegative atom (e.g., oxygen, nitrogen, and sulfur...
The meaning of HYDROGEN BOND is an electrostatic attraction between a hydrogen atom in one polar molecule (as of water) and a small electronegative atom (as of oxygen, nitrogen, or fluorine) in usually another molecule of the same or a different polar su
Which of the following bonds has the highest bond energy ? View Solution Nitrogen , oxygen and fluorine are the highly electronegative elements. When they are tied to a hydrogen atom to form covalent bond, the electrons of the covalent bond are shifted towards the more electronegative atom.This...
one water molecule is electrostatically attracted to the electropositive oxygen atom of the nearby water molecule. Hydrogen bond formation in water accounts for the latter’s distinctive properties such as high boiling point (100 °C), high surface tension, specific heat, and heat of vaporization....
