Hydrogen has a low electronegativity while fluorine has an extremely high electronegativity.
Please see http://wiki.answers.com/Q/Which_is_more_polar_fluorene_or_florenone
Hydrogen gas, H2, is nonpolar because both hydrogen atoms have the same electronegativity, so the difference in electronegativity is 0, which means the bond is nonpolar, and since this is the only bond, the gas is nonpolar.
Hydrogen fluoride is a polar molecule due to the electronegativity difference between hydrogen and fluorine atoms. The fluorine atom attracts the electron pair towards itself, creating a partial negative charge on the fluorine and a partial positive charge on the hydrogen, resulting in a polar covalent bond.
No, water is not the only molecule that is polar. Other examples of polar molecules include ammonia (NH3), hydrogen fluoride (HF), and hydrogen chloride (HCl). These molecules have an uneven distribution of charge, causing a separation of positive and negative regions.
Yes, hydrogen fluoride is very polar.
No, despite the electronegativity difference between hydrogen and fluorine, hydrogen fluoride is a polar molecule due to the uneven distribution of electron density caused by the fluorine atom's higher electronegativity. This results in a partial negative charge on the fluorine atom and a partial positive charge on the hydrogen atom, making the molecule polar.
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.
Yes, potassium fluoride is a polar molecule. The potassium cation has a positive charge, while the fluoride anion has a negative charge, resulting in an overall dipole moment for the molecule.
Polar molecules have partial negative and partial positive charges on opposing sides. They have a net dipole as a result of the opposing charges.
BeF2 is non-polar as it is (strangely) covalent in nature and as such, the molecule has a linear shape which produces a non-polar molecule.
Yes, hydrogen fluoride has polar covalent bonds. In a polar covalent bond, the electrons are not shared equally between the two atoms. In the case of hydrogen fluoride, the fluorine atom is more electronegative than the hydrogen atom, so it attracts the shared electrons more strongly, leading to a partial negative charge on the fluorine and a partial positive charge on the hydrogen.
yes it is a non polar molecule
