The electronegativity of Se is 2.55, while that of hydrogen is 2.20.

This is due to the presence of <strong>lone pairs<\/strong> of electrons on the selenium atom. Selenium, like oxygen in water, has two lone pairs of electrons, which result in a bent molecular geometry according to the <strong>VSEPR theory<\/strong> (Valence Shell Electron Pair Repulsion).<\/li>\n\n\n\n<li>In a bent structure, the bond dipoles do not cancel each other out, as they would in a linear structure.
