No d ans is wrong. Cl tends to be more packed with d shared electron b/w H and Cl this make H and Cl to form a partial ionic xracter because of dipole attraction. So is because Cl has a greater electron affinity than H

The property of chlorine that makes hydrogen chloride (HCl) more ionic than chlorine molecules (Cl2) is its strong electronegativity. Chlorine's high electronegativity causes it to attract electrons in the H-Cl bond more strongly, creating a polar bond with partial charges, while in Cl2, the bond is nonpolar because the two chlorine atoms share electrons equally.
