Hydrogen bonding is a type intermolecular attractive force and is a special class of dipole-dipole interaction. Its dipoles form between hydrogen and either nitrogen, oxygen, or fluorine (these are the nonmetals with the strongest electronegativities). The strong electronegativities of these three ...
What property of water is due to hydrogen bonds? What is the boiling point of F2? How do you determine the intermolecular forces acting on a molecule (London dispersion, dipole-dipole, hydrogen bonds, etc.) when given the Lewis structure? How is electronegativity related to covalent bonding?
For a cleavage of this type to be feasible, the charge separation created upon breaking of the N–Cα backbone bond must be quickly annihilated. In this work, we show, using density functional computations, that specific hydrogen-bonding motifs and structural rearrangements involving proton ...
Hydrogen bonding in ionic liquids based on the 1-(2′-hydroxylethyl)-3-methylimidazolium cation ([C2OHmim]+) and various anions ([A]−) of differing H-bond acceptor strength, viz. hexafluorophosphate [PF6]−, tetrafluoroborate [BF4]−, bis(trifluoromethanesulfonimide) [Tf2N]−, trifluo...
You can think about chemical bonding in a similar manner. The key to determining if the bond between two atoms is polar has to do with the behavior of theelectrons, which themselves are the key to chemical bonding. They are shared if both atoms want the electrons an equal amount, and the...
How does pH affect hydrogen bonding? « on: November 19, 2020, 06:45:11 PM » Would a basic solution (water and KOH) have less H-bonding capability than a neutral solution? There are a lot of factors here that make it hard to guess at. Anyone have any data, link, or just a...
Role of hydrogen bonding in supramolecular architectures Self-healing materials using supramolecular interactions Molecular cages and their use in encapsulation Supramolecular chemistry in organic electronics Design of supramolecular hydrogels for biomedical applications Chirality in supramolecular systems Supramolecular...
Determine which element is the least electronegative, or has the weakest pull on the electrons, by looking on an electronegativity chart or by examining the element's position relative to the other elements on the Periodic Table. Elements generally increase in electronegativity from left to right an...
how the structure of DNA allows it to serve as the basis for inheritance Explain the function of all molecules involved in DNA replication. How are DNA double helices stabilized other than through hydrogen bonding between bases? How would a mutation that inserts 3 nucleotides into a DNA...
