carbon-hydrogen bonds of alkanes are not polar.
Fluorine and hydrogen
Acetone has the formula (CH3)2CO. The bonds between the carbon and hydrogen atoms are covalent, and are sigma bonds. The bonding beween carbon and oxygen is a double bond. The carbon atom is sp2 hybridised. The bond involves a sigma bond and a pi bond This bond is polar because of the difference in electronegativity of carbon and oxygen.
Two atoms of different elements cannot form non-polar covalent bonds.
The hydrogen-oxygen and carbon-oxygen bonds are polar covalent bonds. In turn, these polar covalent bonds can lead to hydrogen bonds forming between ethanol molecules and some other molecules.
Yes...hydrogen fluoride (HF) has polar covalent bonds
Bonds between carbon and hydrogen are non-polar.
Fluorine and hydrogen
Sodium iodide has ionic bonds, which are always polar. Carbon dioxide and hydrogen gas both have molecular (covalent) bonds; the ones in carbon dioxide are polar and those in elemental hydrogen molecules (H2) are nonpolar.

Yes...hydrogen fluoride (HF) has polar covalent bonds
Yes. The triple bond between the two carbon atoms in an ethyne molecule is totally nonpolar, and the bonds between carbon and hydrogen are generally considered non polar also even though they have a slight polar character. Note, however, that the carbon to hydrogen bonds are sufficiently polar to react with very strong bases to produce C2-2 anions such as those in calcium carbide.
Hydrogen bonds occur between polar molecules such as water.
Within the molecule, the bonds are covalent bonds. Between water molecules, they're hydrogen bonds.
Carbon hydrogen trichloride, more commonly called trichloromethane or chloroform is polar.
