covalent
That statement is incorrect. HF is a polar molecule because fluorine is more electronegative than hydrogen, causing the electron density to be pulled closer to the fluorine atom. As a result, HF has a partial positive charge on the hydrogen atom and a partial negative charge on the fluorine atom.
The two hydrogen-oxygen bonds in a water molecule allow it to form more hydrogen bonds with adjacent molecules than hydrogen fluoride can with its one hydrogen-fluorine bond. As a result, water has a stronger attraction between molecules.
In a molecule of water, you have a bunch of unshared electrons on the oxygen side of the molecule (the negative end) and no electrons and two hydrogen nuclei on the hydrogen end (the positive end.) This makes for very strong polarity, since a positive end and a negative end can be thought of as poles. Fluorine, on the other hand, is a diatomic element consisting of two fluorine atoms covalently bonded together. This means each of the two fluorine atoms contribute one electron to the bond. The remaining six from each atom are on the other side of the molecule from the bond. Six on one side and six on the other means no difference in charge across the length of the molecule, so there are no poles.

Selenium fluoride bond is polar because fluorine is more electro-negative than selenium. Hence the shared paired of electrons are more towards fluorine giving fluorine a partial negative charge and selenium a partial positive charge.
A molecule with hydrogen bonded to O, N, or F (Apex)
yes
No. Hydrogen fluoride is inorganic as it contains only hydrogen and fluorine.
It is hydrogen fluoride with chemical formula HF. It contains one fluoride atom and one hydrogen atom per hydrogen fluoride molecule.
Hydrogen fluoride is a colourless gas with chemical formula HF. It is a covalent compound with one hydrogen and one fluorine atom per molecule.
H2 + F2 -> 2HFhydrogen + fluorine -> hydrogen fluorideOne molecule of hydrogen reacts with one molecule of fluorine to produce two molecules of HF.
Hydrogen has a low electronegativity while fluorine has an extremely high electronegativity.
Yes, hydrogen bonds do exist between molecules of hydrogen fluoride. This is because hydrogen fluoride molecules are quite small and are very polar due to the high electronegativity difference of hydrogen and fluorine. As a result, the hydrogen end of each molecule is slightly positive while the fluoride end is slightly negative. The slightly positive hydrogen end of one molecule will be attracted to the slightly negative fluoride end of another molecule, thus forming a hydrogen bond.
'Fluoride atom'. ???? The fluorine ATOM is 'F' The fluorine molecule is 'F2'. The Fluoride ION is 'F^-' NB When an atom becomes a charged species, it is no longer an atom , but an ION. The suffix '--ide' indicates it is an ion, not an atom. So 'Fluoride atom' is a nonsense. It is either 'Fluoride ion' or Fluorine atom'.
The two hydrogen-oxygen bonds in a water molecule allow it to form more hydrogen bonds with adjacent molecules than hydrogen fluoride can with its one hydrogen-fluorine bond. As a result, water has a stronger attraction between molecules.
