What is the relashionship between hydrogen bonds and polar attractions?
Lexx0111
Abstract The emission spectra of styrene (ST)-triethylamine (TEA) systems were measured under steady-state illumination conditions in some tetrahydrofuran (THF)-protic solvent mixtures. The fluorescence spectrum of the ST-TEA system in THF consists of two bands (band A at 304 nm (fluorescence of ST) and band B at 460 nm (emission from an exciplex)). The intensity of band A increased and that of band B decreased with increasing amounts of protic solvents in THF-protic solvent mixtures. The increase in the intensity of band A was explained by the decrease in the concentration of free amine owing to the hydrogen-bonding interaction (or protonation) between TEA and protic solvents. The decrease in the intensity of band B was considered to be caused by the decrease in the concentration of free amine upon the addition of protic solvents and the enhanced conversion of the exciplex to an ion pair with increasing solvent polarity. The polar effect was expressed as a function of the relative permittivity of the solution.

∙ 7y agoThe two hydrogen atoms and one oxygen atom within water molecules (H 2O) form polar covalent bonds. While there is no net charge to a water molecule, the polarityof water creates a slightly positive charge on hydrogen and a slightly negative charge on oxygen, contributing to water's properties of attraction.

Which attractions are most prevalent between molecules of HF in the liquid phase?
Hydrogen bonds
Weak bonds forming a bridge between water molecules are called?
Adjacent water molecules are connected by the electrical attraction between the oxygen of one water molecule and the hydrogen of another water molecule. This type of bonding is called hydrogen bonding.
What is the intermolecular forces of HClO?
There are dipole attractions and hydrogen bonds present in HClO.
Why intramolecular forces stronger?
Intramolecuar forces are covalent bonds these involve the sharing of electrons. Intermolecular bonds are electrostatic in origin such as hydrogen bonds and London disprion forces which involve attractions between small charges.
The boiling temperature of water is so much higher than that of methane because water molecules are?
d.polarWater molecules are polar covalent and therefore form attractions between the molecules called hydrogen bonds. Much of the heat that goes into raising the temperature of water to its boiling point goes to breaking the hydrogen bonds first.
What is the differace between covalent and hydrogen bonds?
Covalent bonds share electrons but hydrogen bonds don't. The latter is a special incident of dipole attractions.
What are the weak chemical attractions between water molecules called?
Hydrogen bonds.
What hydrogen bonds?
extra strong intermolecular attractions between polar molecules -apex
What are hydrogen-bonds?
extra strong intermolecular attractions between polar molecules -apex
Which attractions are most prevalent between molecules of HF in the liquid phase?
Hydrogen bonds
Hydrogen bonds are what kind of bonds?
strong polar attractions between molecules involving h, f, o, and n
What kinds of bonds are hydrogen bonds?
There are a few types of hydrogen bonds. Fluorine, oxygen, and nitrogen are the elements that typically form bonds with hydrogen.
What bonds are broken when water evaporates into water vapor?
Hydrogen Bonds.(Hydrogen bonding is another term for the dipole-dipole attractions between H2O molecules.) A Hydrogen bond is between a H atom in one molecule and either a O, N, or F atom in another.
Weak bonds forming a bridge between water molecules are called?
Adjacent water molecules are connected by the electrical attraction between the oxygen of one water molecule and the hydrogen of another water molecule. This type of bonding is called hydrogen bonding.
