Identify the intermolecular forces responsible for the attraction between H2O molecules. How does a polar covalent bond contribute to formation of hydrogen bond? The melting point of methane is low, so why is that in terms of intermolecular forces? Is a hydrogen bond stronger than a covalent...

Hydrogen bonding plays an essential role on intermolecular forces, and consequently on the thermodynamics of materials defined by this elusive bonding character. It determines the property of a vital liquid as water as well as many processes crucial for life. The longstanding controversy on the ...
is a type of attractive intermolecular force that exists between two partial electric charges of opposite polarity. Although stronger than most other intermolecular forces, the hydrogen bond is much weaker than both the ionic bond and the covalent...

Hydrogen bonding, interaction involving a hydrogen atom located between a pair of other atoms having a high affinity for electrons; such a bond is weaker than an ionic bond or covalent bond but stronger than the van der Waals forces. Hydrogen bonds can exist between atoms in different molecules...
How does a polar covalent bond contribute to the formation of a hydrogen bond? Intermolecular Forces: In addition to covalent and ionic bonds, there are other forces that exist between molecules. Molecules can transiently attain partial charges because of the movement of electrons, which...
Briefly describe the type of bond: Covalent. Why are hydrogen bonds the strongest intermolecular forces? Identify and explain the type(s) of intermolecular bonds between molecules of NH_3. Describe the bonding (using valence bond theory) of the Group 4A atoms in each of ...
Acting in the covalent bond, the electric forces of the nuclear electron interaction and the magnetic forces, together with electrostatic forces of atoms attractingwith opposite charges, correlate with interatomic distances of atoms in the molecule (in the X–H bond distance), and this is observed...
More than 80 years ago, Linus Pauling recognized the existence of a strong bond between an atom of hydrogen and two other atoms and the importance of the hydrogen bond in protein structure. Hydrogen bonds are indeed essential for protein folding and stability and protein-protein interactions. They...
