Oxygen and Nitrogen in Competitive Situations: Which is the Hydrogen-Bond Acceptor? EJMC 2012, 2, 1509-1513.Boehm, H.-J.; Brode, S.; Hesse, U.; Klebe, G. Oxygen and nitrogen in competitive situations: which is the hydrogen-bond acceptor?. Chem.-Eur. J. 1996, 2, 1509-1513....
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 ...
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...
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
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...
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
Steering acidic oxygen reduction selectivity of single-atom catalysts through the second sphere effect Article Open access 30 December 2024 Introduction Enzymes-inspired catalysts composed of active sites and protein binding pockets interacting with a substrate have been a long-standing goal of heterogeneo...
Atom A is electronegative, the A–H bond being therefore slightly ionic in character, and atom B possesses an area of basicity such as lone pairs on nitrogen, oxygen and halogen or π electron rings (here B is a group of atoms) in certain aromatic systems. The energies of interaction are...
between hydrogen and carbon atoms of different chloroform molecules, between hydrogen and nitrogen atoms of neighboring ammonia molecules, between repeating subunits in the polymer nylon, and between hydrogen and oxygen in acetylacetone. Many organic molecules are subject to hydrogen bonds. Hydrogen bond:...
