CCL2F2: Polar or Nonpolar?

Whether CCl2F2 (dichlorodifluoromethane), also known as Freon-12, is polar or nonpolar depends on its molecular geometry and the electronegativity differences between the atoms.

• Molecular Geometry: CCl2F2 has a tetrahedral geometry around the central carbon atom. This is because carbon has four bonding pairs and no lone pairs.

• Electronegativity: Fluorine is significantly more electronegative than both carbon and chlorine. Chlorine is also more electronegative than carbon, but to a lesser extent.

• Bond Dipoles: The C-F bonds are highly polar, with a dipole moment pointing towards the fluorine atoms. The C-Cl bonds are also polar, but less so than the C-F bonds, with the dipole moment pointing towards the chlorine atoms.

• Overall Molecular Dipole Moment: Due to the tetrahedral geometry, the bond dipoles do not completely cancel each other out. Although it's close to zero, there is a net dipole moment pointing in the direction of the more electronegative fluorine atoms.

• Conclusion: Therefore, CCl2F2 is considered a polar molecule.
