Quantum chemical calculations have been performed to investigate the interaction of the neutral H2B radical with hydrogen cyanide (HCN) and hydrogen iso-cyanide (HNC) at the MP2/aug-cc-pVTZ level. The results show that a weak hydrogen bond and a strong covalent interaction can be formed ...
Which of the following bonds has the highest bond energy? View Solution 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...
Hydrogen bond is an electrostatic force of attraction between partial positive charge of hydrogen atom bonded to an electronegative atom or group and electron-rich another electronegative atom possessing lone pair of electrons. From: De Novo Peptide Design, 2023 ...
Imine ExchangeHydrogen Bonding CatalysisDynamic SystemsSolid-Supported CatalystThe reversibility of imine bonds has been exploited to great effect in the field of dynamic covalent chemistry, with applications such as preparation of functional systems, dynamic materials, molecular machines, and covalent ...
with excellent mechanical compliance. On one hand, H-bonding could modify the intermolecular interaction through multiple interactions, thereby manipulating the stacking behaviors of molecules and facilitating charge carrier transport. On the other hand, the resultant non-covalent intermolecular crosslinking ...
Proton activity at the electrified interface is central to the kinetics of proton-coupled electron transfer (PCET) reactions for making chemicals and fuels. Here we employ a library of protic ionic liquids in an interfacial layer on platinum and gold to alter local proton activity, where the int...

Define Hydrogen bonds. Hydrogen bonds synonyms, Hydrogen bonds pronunciation, Hydrogen bonds translation, English dictionary definition of Hydrogen bonds. n. A chemical bond in which a hydrogen atom of one molecule is attracted to an electronegative atom
Can these molecules of hydrogen bond with each other? Is the O-H bond in water ionic, polar covalent, or nonpolar covalent? Explain. Is the bond formed between carbon and hydrogen ionic, polar covalent, or nonpolar covalent? Explain.
leading to the well-known crystal structure of snowflakes. In liquid water, the distance between adjacent molecules is larger and the energy of the molecules is high enough that hydrogen bonds are often stretched and broken. However, even liquid water molecules average...
