Electron and molecular geometries

Question

Electron geometry of H2S?

Molecular geometry of H2S?

Electron geometry of CHCl3?

Molecular geometry of CHCl3?

Answer 1

H₂S is similar to water (H₂O). Sulfur is the central atom with 2 bonding pairs of electrons to each Hydrogen and 2 lone pairs of electrons.

Electron geometry = Tetrahedral; Molecular geometry = Bent

CHCl₃ --> Carbon is the central atom bonded to one H and 3 Chlorines. Total of 4 bonding pairs of electrons and zero lone pairs.

Electron geometry = Tetrahedral; Molecular geometry = Tetrahedral
