Question
In XeO3, the xenon-oxygen bonds are:A.nonpolar, because the electron affinity of Xe is close to zero.B.nonpolar, because the electronegativities of Xe and O are nearly equal.C.polar, because the electronegativity of Xe is much higher than the electronegativity of O.D.polar, because the electronegativity of Xe is much lower than the electronegativity of O.
Solution
The correct answer is D. The xenon-oxygen bonds in XeO3 are polar because the electronegativity of Xe is much lower than the electronegativity of O.
Here's why:
-
Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. The Pauling scale is the most commonly used electronegativity scale.
-
On the Pauling scale, oxygen has an electronegativity of 3.44, while xenon has an electronegativity of 2.6.
-
Because oxygen is more electronegative than xenon, it will attract the bonding pair of electrons more strongly. This creates a dipole moment, where the oxygen end of the bond has a partial negative charge and the xenon end has a partial positive charge.
-
Therefore, the xenon-oxygen bonds in XeO3 are polar.
Similar Questions
Based on its molecular structure, is XeO3 a polar molecule?A.Yes, because the Xe=O bonds are polar and any molecule with polar bonds is a polar molecule.B.No, because the Xe=O bonds are nonpolar.C.Yes, because the Xe=O bonds are polar and have a geometry that gives the molecule a net dipole.D.No, because the Xe=O bonds are polar but have a geometry that causes the dipoles to cancel.
