The electron pair in the bond is closer to the more electronegative atom, causing a partial negative charge on it and a partial positive charge on the less electronegative atom. This creates a polar covalent bond between the atoms.
As posed, the question makes no sense. Because fluorine is the most electronegative of all elements, absolutely anything that it bonds to must inevitably be less electronegative. So no general comment or answer is possible beyond what follows from its electronegativity - it has a high tendancy to gain an electron.
When hydrogen is attached to a more electronegative element, it tends to become more polarized due to the higher electronegativity difference. This can result in the hydrogen atom carrying a partial positive charge, making it more likely to participate in hydrogen bonding or interact with other electronegative species.
No, CH3Cl (chloromethane) does not exhibit hydrogen bonding. Hydrogen bonding occurs between molecules with hydrogen atoms bonded to highly electronegative atoms such as nitrogen, oxygen, or fluorine, which would result in a significant electronegative difference between hydrogen and the other atom. In CH3Cl, the hydrogen atom is bonded to carbon, which is less electronegative than hydrogen.
When the range of electronegativity between the atoms are really high. For example, hydrogen has 2.20 elctronegativity and fluorine has 3.98 and the range between them is 1.78. Compared to like nitrogen (3.04) and oxygen (3.44), whose range is 0.4, the hydrogen and fluorine will have a strong dipole-dipole force.
Fluorine is more electronegative than lithium and chlorine because it has a greater nuclear charge and a smaller atomic size. These factors result in a stronger attraction for electrons in the fluorine atom, making it more electronegative compared to lithium and chlorine.

For hydrogen atoms to have the ability to create hydrogen bonds they must be bonded to an electronegative atom such as fluorine or oxygen. (This creates a partial positive charge on the hydrogen.) Since hydrocarbons are composed of only hydrogen and carbon there is no polarity in the bonds (electronegativity difference of 0.4).
Oxygen, nitrogen, and fluorine are highly electronegative elements, meaning they tend to attract electrons strongly. This high electronegativity creates a significant dipole in molecules, where the hydrogen atom bonded to these elements acquires a partial positive charge. As a result, the hydrogen atom can strongly interact with the lone pairs of electrons on adjacent electronegative atoms, forming strong hydrogen bonds. These interactions significantly influence the physical properties of substances, such as boiling and melting points.
In hydrogen fluoride (HF), the electronegativity values are approximately 2.1 for hydrogen and 4.0 for fluorine, based on the Pauling scale. This significant difference in electronegativity (about 1.9) indicates a strong polar covalent bond, with fluorine attracting the bonding electrons more strongly than hydrogen. As a result, HF has a dipole moment, making it a polar molecule.

No element on its own can form hydrogen bonds. Only compounds where hydrogen is bonded to nitrogen, oxygen, or fluorine. Hydrogen bonded to carbon and sulfur (selenium?) can also participate in strong hydrogen bonding when these atoms are bound to electronegative elements or ligands. (Eg. HCN, CHCl3, CH3COSH)
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.
