The property of chlorine which causes hydrogen chloride to be more ionic than the chlorine molecules is its
- electrovalency
- electron affinity
- electropositivity
-
electronegativity
The correct answer is: D
Explanation
Electronegativity is the tendency of an atom to attract electrons when forming a chemical bond. In HCl, the chlorine atom's higher electronegativity causes it to attract the bonding electrons, resulting in a partial negative charge on chlorine and a partial positive charge on hydrogen.
