Guida verificata passo dopo passo1
Identify the central atom in the molecule. In CS2, the central atom is carbon (C).
Determine the number of electron groups around the central atom. In CS2, carbon is bonded to two sulfur atoms, forming two double bonds. Each double bond counts as one electron group, so there are two electron groups around the carbon atom.
Use the VSEPR (Valence Shell Electron Pair Repulsion) theory to predict the electron geometry. According to VSEPR theory, if there are two electron groups around the central atom, the electron geometry is linear.
Consider the molecular geometry, which is determined by the arrangement of atoms. Since there are no lone pairs on the central carbon atom and only two bonding pairs, the molecular geometry is also linear.
Review the options provided: Linear, Bent, Trigonal planar, Tetrahedral. Based on the analysis, the electron geometry for CS2 is linear.
