Determine the electron geometry for the carbon disulfide molecule, CS 2 . A. Linear B. Bent C. Trigonal planar D. Tetrahedral

Determine the electron geometry for the carbon disulfide molecule, c s 2. So we take a look here, we see that we have our central element carbon, and it is connected to 2, so 2 surrounding elements. So we're gonna say all it has are 2 electron groups. So think about our memory tools, 2 electron groups. Remember, there are 2 points in a straight line, And because of that, because there's 2 groups, 2 electron groups here, this would be linear. Okay? So here we'd say the electron geometry is linear, and remember we use the memory tool that there are 2 points in a straight line. 2 referring to the 2 electron groups attached to the carbon atom.

Verified step by step guidance

Identify the central atom in the molecule. In CS2, carbon (C) is the central atom.

Determine the number of electron groups around the central atom. In CS2, there are two double bonds between carbon and each sulfur atom, resulting in two electron groups.

Use the VSEPR (Valence Shell Electron Pair Repulsion) theory to predict the electron geometry. According to VSEPR theory, a molecule with two electron groups around the central atom will have a linear electron geometry.

Consider the absence of lone pairs on the central atom. In CS2, carbon has no lone pairs, which means the molecular geometry is the same as the electron geometry.

Conclude that the electron geometry for the carbon disulfide molecule, CS2, is linear.
