The electronegativities of F and H are respectively 3.98 and 2.1, and the difference is 1.88
No, HF (hydrogen fluoride) is a covalent compound. It consists of a covalent bond between hydrogen and fluorine atoms due to the sharing of electrons. Ionic compounds typically involve the transfer of electrons between metal and nonmetal atoms.
fluorine is more electronegative than hydrogen.hence it would pull electrons of shared pair towards itself more strongly. Then a hydrogen bond would be formed between HF molecules.Hence it is polar covalent.H-F.........H-F..........H-F.......H-F
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.
The electronegativity of potassium (K) is 0.82 and the electronegativity of fluorine (F) is 3.98. To find the electronegativity of KF, you take the difference between the two values: 3.98 - 0.82 = 3.16. Therefore, the electronegativity of KF is 3.16.
The electronegativity of N O and F are 3.0 3.5 and 4 respectively according to the Pauling's scale. The electronegativity difference between N and F is greater than the difference between O and F. So, the prior bond is expected to be more polar.

Polar covalent. There is a significant difference in electronegativity between C and F.

The polarity of the molecule will depend on the electronegativities of the 2 atoms involved. For example, a molecule of F2 where F binds to F will be non polar as there is no difference in electrnegativities. However, a molecule of HF will be polar because F is more electronegative than is H.
Polar covalent. There is a significant difference in electronegativity between C and F.
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.
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
The bond between hydrogen and fluorine is not a covalent bond. When hydrogen bonds with oxygen, nitrogen, or fluorine, then it is called a hydrogen bond. Hydrogen bonds will be stronger than a regular covalent bond, so the electronegativity difference will be higher.
The electronegativity of N O and F are 3.0 3.5 and 4 respectively according to the Pauling's scale. The electronegativity difference between N and F is greater than the difference between O and F. So, the prior bond is expected to be more polar.
The net ionic equation for the reaction between hydrofluoric acid (HF) and sodium hydroxide (NaOH) is: HF + OH- -> F- + H2O
