The only true non-polar bond is between atoms with identical electronegativity. An HI molecule with an electronegativity difference of 0.4 between H and I would therefore have moved very little of the binding electrons towards atom I. The polarity of the bond is indeed a continuum, not black and white.
All heteronuclear diatomic molecules are non-polar. Hydrogen iodide (HI) Note the symmetry of the molecule: the top and bottom as well as the left and right are not mirror images of each other when they split. The molecule is also called polar because the bond is polar.
Hydrogen iodide is a diatomic molecule formed by a covalent bond. The electronegativity of hydrogen is about 2.2 while iodine has an electronegativity of about 2.66. When the difference in electronegativity in a bond is between 0.5 and 1.7, the bond is usually formed from a polar covalent bond.

It’s actually just that HCL is a polar molecule because chlorine has a higher electronegativity than hydrogen. It then attracts electrons to pass more time, giving it a negative charge and hydrogen a positive charge. HCL is neither polar nor apolar. Is
Properties of organic compounds
Polar molecules occur when there is a difference in electronegativity between bonded atoms. Non-polar molecules occur when electrons are evenly distributed among the atoms of a diatomic molecule or when the polar bonds of a larger molecule interfere with each other.
Non-polar covalent bonds are a type of chemical bond in which two atoms share a pair of electrons. The polar covalent bond is a type of chemical bond in which a pair of electrons is unevenly distributed between two atoms.
Hydrogen has an electronegativity of 2.1 and chlorine has an electronegativity of 3.0. The electron pair that binds HCl together moves to the chlorine atom because it has a higher electronegativity value. A bond in which the electron pair is moved onto an atom is called a polar covalent bond.
Polar molecules. A molecule is polar when it has an acute dipole. The bonds CH and CN are polar. Each NH bond is polar because nitrogen is more electronegative than hydrogen, so each hydrogen atom receives a partially positive charge (δ +) and the nitrogen atom receives a partially negative charge (δ).
Boron trichloride or BCl3 is not polar. The three chlorine atoms are negatively charged and a boron in the center has the same but positive charge. Boron is in the center of the molecule and has three valence electrons, so it balances the three chlorides.
Salt or sodium chloride (NaCl) is a good example of ionic bonds. Sodium (Na) has 1 valence electron and chlorine (Cl) has 7 electrons in its outermost orbit. If the sodium were to lose its valence electron, the next bowl would be full. But it would also turn sodium into a positive ion.
HCl, also called hydrochloric acid, has a covalent bond. The hydrogen atom (H) shares an electron with chlorine (Cl) to form the bond.
Sodium chloride is an ionic compound. Many bonds can be covalent in one situation and ionic in another. For example, hydrochloric acid, HCl, is a gas to which hydrogen and chlorine are covalently bonded, but when HCl is bubbled through water, it ionizes completely to give H + and Cl di a solution of hydrochloric acid.
The bonds with H2S are covalent because hydrogen has an electronegativity of about 2.2 and sulfur has a 2.56. Since hydrogen has lower electronegativity, it is a reducing agent and an oxidizing agent of sulfur. Although the difference is minor, for non-metals they have two electronegativities.
The most positive hydrogen on an HF molecule will be attracted to one of these lone pairs on a neighboring HF molecule. It is a hydrogen bond. Hydrogen bonds are attractions between a hydrogen + hydrogen on one molecule and a single pair on a strongly electronegative atom (N, O or F) on another molecule.
The hydrofluoric acid (HF) molecule is polar due to polar covalent bonds in the covalent bond, electrons are moved to the more electronegative fluorine atom. The polar covalent bond, HF. The resulting hydrogen atom carries a partially positive charge.
