An OH molecule is polar. Because the oxygen has a higher electronegativity, it will have the shared electron much more than the hydrogen. Therefore the oxygen end of the molecule will develop a slightly negative charge, and the hydrogen end a slightly negative one.
It is fairly nonpolar. Since the electronegativity of hydrogen is 2.1, and the electronegativity of phosphorus is 2.19, there is not quite as much difference in electronegativities to render a sufficient dipole moment in order to make for a polar bond. However, the slightly large electronegativity of P over H yields a minor one.
nonpolar!
Polar due to different Electronegativities :D
It is polar due to different electronegativities between the H and F atoms (fluorine is MUCH more electronegative than hydrogen).
The bond between H and F in HF is very polar.
Electronegativity Difference HF = 1.9 = ionic bond HC = 0.4 = nonpolar covalent HH = 0 = nonpolar covalent HN = 0.9 = polar covalent HN is the more polar bond. HF is not polar covalent, it is ionic.
Unlike the other 3 binary acids comprised of one hydrogen atom and one halogen atom (HF, HCl, and HBr), the bond between hydrogen and iodine would be nonpolar, based on their electronegativity values on the Pauling Scale. Since nonpolar covalent bonds exist when the difference in electronegativity is below 0.5, the H---I bond ought to be considered nonpolar, since the difference is only 0.4.
Polarity of HF is nonpolar and it's molecular shape is linear.
PolarHydrochloric acid (HCl) is polar covalent because the electrons are more attracted to the chlorine and not the hydrogen. The hydrogen will sustain a slight positive charge, and chlorine will sustain a slight negative one, making the compound polar. The affinity to electrons is called electronegativity. We can recognize polar, non-polar, and ionic bonds based on the difference between electronegativities in the atoms of the compound. When the difference in electronegativity between two atoms is between about 0.4 and 1.7, then the bond is said to be polar covalent. A difference between 0 and 0.4 is nonpolar. Hydrogen's electronegativity is 2.2 and chlorine's is 3.16. The difference between the two is 0.96, indicating that it's a polar bond.

HF is polar and linear. But CO2 is nonpolar because it is linear. It has two equally polar bond pulling electrons in opposite directions and cancel each other out.
HF is a weak polar bond
Electronegativity Difference HF = 1.9 = ionic bond HC = 0.4 = nonpolar covalent HH = 0 = nonpolar covalent HN = 0.9 = polar covalent HN is the more polar bond. HF is not polar covalent, it is ionic.
It is polar covalent bond because electrons forming the bond are unequally distributed.
Yes but it is polar
Covalent. The bond is polar due to the high electronegativity of fluorine.
A good candidate would be the bond in HF.
HF has a polar covalent bond.
Fluorine atoms have a covalent bond between each other to form a covalent molecule. Fluorine bonded to a metal will have ionic bonds. Fluorine bonded to a non-meatl will have polar covalent bonding.
Hydrogen fluoride, with the symbol HF, is a polar molecule. This is due to fluorine being more electronegative compared to hydrogen. This creates a difference in electronegativity, which makes HF a polar bond.
a very polar, single, covalent bond, yes. This would be an ionic bond. The electronegativity of Hydrogen is about 2.2 and the electronegativity of Fluorine is about 4.0. The difference is 1.8 which is greater than 1.7, the minimum difference for an ionic bond. Or it is (at least) a very polar-covalent bond. Figures 1.7 or 1.8 are in the 'discussion' range
yes it is a polar covalent bond. the difference of electronegativities of H and F is 1.9 , it should be an ionic bond but the ratio of atomic sizes of both the atoms is responsible for polar covalent bond.
