Answer:

See explanation

Explanation:

Usually, the central atom in a molecule is often the atom having the least electronegativity in the compound.

In CO2F^-, the central atom is carbon. The structure is related to the structure of CO2. In CO2F^-, carbon is sp hybridized. The molecule is linear.

In S2Cl2, sulphur is the central atom. There are two central sulphur atoms each connected to one chlorine atom. The sulphur atoms are sp3 hybridized with two lone pairs on each sulphur atom. The molecular geometry is bent.

[tex]CO_2F^-[/tex] has a flat geometry, with carbon as the central atom. On the other hand, [tex]S_2Cl_2[/tex] has a folded geometry, with two sulfur atoms as the central atoms.

We can arrive at this answer because:

  • The central atoms of a molecule are determined by the level of attraction of the atoms during binding.
  • The atom that has less electronegativity is the one that is positioned in the center of the molecule and has its atoms attracted and pulled by more electronegative molecules that are positioned on the sides and has its electrons closer to it.
  • During this binding and because of the difference in electronegativity, the molecule can assume a flat or folded geometrical position.

In this case, when we observe the position of the atoms and the geometry of the molecules of [tex]CO_2F^-[/tex] and [tex]S_2Cl_2[/tex] we can see that they are flat and folded as shown in the figure below.
