Answer: The electron pair geometry is linear
Step-by-step explanation:
Carbon in carbon disulphide is surrounded by four electron pairs which is ordinarily expected to lead to a tetrahedral electron pair geometry according to Valence shell electron pair repulsion theory (VSEPR). However, the observed shape is linear due to the fact that double bonds cause more repulsion than single bonds. The double bonds force the molecule into a linear arrangement as in Carbon IV oxide molecule. See image attached for structures.
