The molecular geometry of carbon disulfide (CS₂) is linear.
Explanation: Carbon disulfide (CS₂) consists of one carbon atom and two sulfur atoms. The carbon atom is in the center, with the two sulfur atoms on either side. The carbon atom forms double bonds with each sulfur atom, resulting in a linear arrangement. This linear geometry is due to the sp hybridization of the carbon atom, which creates two regions of electron density around the carbon atom, leading to a bond angle of 180 degrees.
