Which of the following statements is TRUE for the covalent molecule HCl? Answer Chlorine is more electronegative and the shared electron pair is likely to be found closer to the hydrogen atom. Chlorine is more electronegative and the shared electron pair is likely to be found closer to the chlorine atom. Hydrogen is more electronegative and the shared electron pair is likely to be found closer to the hydrogen atom. Hydrogen is more electronegative and the shared electron pair is likely to be found closer to the chlorine atom.
