Determine the point group of SF5Cl.<\/p>\n\n\n\n

The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

The point group of SF\u2085Cl<\/strong> is C\u2084v<\/strong>.<\/p>\n\n\n\n

\n\n\n\n

Explanation<\/h3>\n\n\n\n

To determine the point group of SF\u2085Cl<\/strong> (sulfur pentafluoride chloride), we begin by analyzing its molecular geometry<\/strong> and symmetry elements<\/strong>.<\/p>\n\n\n\n

1. Molecular Geometry:<\/strong><\/h4>\n\n\n\n

SF\u2085Cl is a derivative of SF\u2086 (sulfur hexafluoride), which has an octahedral<\/strong> geometry. In SF\u2085Cl, one of the six fluorine atoms in SF\u2086 is replaced with a chlorine atom. This still results in an octahedral arrangement<\/strong> of six ligands around the central sulfur atom. However, because chlorine is different from fluorine, the molecule is no longer symmetric in all directions<\/strong> like SF\u2086.<\/p>\n\n\n\n

To minimize repulsion (as chlorine is larger than fluorine), the Cl atom preferentially occupies an axial<\/strong> position. So the structure has a square pyramidal shape with:<\/p>\n\n\n\n

    \n
  • Four fluorine atoms in the equatorial plane<\/strong>,<\/li>\n\n\n\n
  • One axial fluorine above,<\/li>\n\n\n\n
  • One axial chlorine below the sulfur atom.<\/li>\n<\/ul>\n\n\n\n

    2. Symmetry Elements in SF\u2085Cl:<\/strong><\/h4>\n\n\n\n
      \n
    • C\u2084 axis<\/strong>: A fourfold rotation axis through the sulfur atom and perpendicular to the equatorial plane (passes through the axial F and Cl atoms).<\/li>\n\n\n\n
    • \u03c3\u1d65 planes (vertical mirror planes)<\/strong>: Four mirror planes exist\u2014two that pass through opposite equatorial F atoms and the axial atoms (F and Cl), and two that bisect the angles between equatorial F atoms.<\/li>\n\n\n\n
    • No center of inversion<\/strong> (i), because replacing one F with Cl breaks that symmetry.<\/li>\n\n\n\n
    • No horizontal mirror plane (\u03c3h)<\/strong>, again due to the Cl substitution.<\/li>\n<\/ul>\n\n\n\n

      With a C\u2084 principal axis<\/strong> and four \u03c3\u1d65 planes<\/strong>, this matches the C\u2084v<\/strong> point group.<\/p>\n\n\n\n

      3. Why Not Other Groups?<\/strong><\/h4>\n\n\n\n
        \n
      • Oh<\/strong>: SF\u2086 has this, but SF\u2085Cl lacks the full symmetry.<\/li>\n\n\n\n
      • C\u2084h, D\u2084h<\/strong>: These require \u03c3h planes or inversion centers, which SF\u2085Cl lacks.<\/li>\n\n\n\n
      • C\u2084<\/strong>: Lacks the mirror planes present in SF\u2085Cl.<\/li>\n<\/ul>\n\n\n\n
        \n\n\n\n

        Final Answer:<\/h3>\n\n\n\n

        Point group of SF\u2085Cl = C\u2084v<\/strong>.<\/p>\n\n\n\n
