The electronegativity is 2.1 for H and 3.0 for Cl. Based on these electronegativities, HCI would be expected to A. have polar covalent bonds with a partial positive charges on the H atoms. B. have ionic bonds and contain H+ ions. C. have nonpolar covalent bonds and contain Hions. D. have nonpolar covalent bonds with a partial negative charges on the H atoms.

Hydrochloric acid, also referred to as muriatic acid, is HCl. It is a component of the hydrogen halides (HX) family. Due to their propensity to lose a proton in a solution.
Hydrogen halides are diatomic inorganic molecules that function as Arrhenius acids. Since the X belongs to the halogen family (group 17), it can be fluorine, chlorine, bromine, or iodine.
In hydrogen chloride, only 17 percent of the hydrogen atom's electron density has been transferred to the chlorine atom. It confirms that the H-Cl bond in the hydrogen chloride is a polar covalent bond, not an ionic bond.
In hydrogen chloride, the chlorine atom is 127.4 x 10⁻¹² m away from the hydrogen atom, giving the compound a 1.05 D dipole moment.
1 D equals 3.33 x 10⁻³⁰ C. m.
The chlorine atom i will have an equal but opposite charge. e. Therefore, the value of the partial charge in the hydrogen chloride compound is 0.027 x 10⁻¹⁸ C.

Mathematically,

% of ionic character = 16(Xa - XB ) + 3.5(XA - Xb )

=16(3-2.1)+3.5(3-2.1)²

= 14.4+2.835

= 17.235%

:. The nature of HCI is 17.2% ionic
