On the usual Pauling scale of electronegativities, the electronegativity of Selenium (Se) is 2.4, while that of chlorine (Cl) is 3.0. Based on these values we should expect the bondingbetween Se and Cl to be
ionic
covalent and nonpolar
covalent and polar with the Se end of the bond slightly negative
covalent and polar with the Cl end of the bond slightly negative
