XeO4; Hybridization - sp3, bond angle -109.5, dipole moments cancel our , the molecule is nonpolar. The Xe-F bonds are all polarized but they cancel one another out so the molecule has no dipole. "In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole or multipole moment. Our experts can answer your tough homework and study questions. Since O is more electronegative than Se, the negative end of the dipole moment is between the two O atoms, and the positive end is around the Se atom. and here XeF4 has no dipole moment. Polar molecules must contain polar bonds due to a difference in electronegativity between the bonded atoms. Such is the case for CO 2, a linear molecule (Figure \(\PageIndex{8a}\)). In SeO 2, the two Se-O bond dipoles do not cancel when summed together, hence SeO 2 has a dipole moment ( is polar). Dipole moment: yes. Can you explain this answer? As H 2 O has two lone pairs so It repels the bond pairs much more and makes bond angle shorter of 104.5 degrees and as NH 3 has one lone pair that repels the three bond pair but not much effectively and strongly as two lone pairs of water repel the bond pair so the bond angle between hydrogen atom of ammonia is 107.5 greater than that of water.

Expert's answer. 3. Structure of XeO3 ⇒3pπ-dπ pi bonds.Structure of XeO4 ⇒4pπ-dπ bonds. 8.125 The SeCl4 molecule is polar because the lone pair of nonbonding electrons in the valence shell of the selenium atom interacts with the bonding pairs of electrons, causing a spatial asymmetry of the dipole moments of the polar Se-Cl bonds. If the individual bond dipole moments cancel one another, there is no net dipole moment.
