Answer: option C. HF
Explanation: A polar bond is a covalent bond between two atoms where the electrons forming the bond are unequally distributed. Fluorine is more electronegative than hydrogen so the electrons in the bond are more closely associated with the fluorine atom than with the hydrogen atom.
H2o is an example of covalent molecule. H2O has two hydrogen atoms bonded to one oxygen atom. The two hydrogen atoms and the oxygen atom are linked together by a covalent bond.Atoms of oxygen are electronegative and attract the sharing of electrons in a covalent bond.
