What is the molecular geometry of the CS2 molecule?

Linear.

The best place to start when trying to figure out a molecule's is its .

Carbon disulfide, ##"CS"_2##, will have a total of ##16## , ##4## from the carbon atom and ##6## from each of the two sulfur atoms.

The central carbon atom will form double bonds with the two sulfur atoms. These bonds will account for ##8## of the ##16## of the molecule.

The remaining ##8## will be placed as lone pairs, two on each sulfur atom.

Now, is determined by the of the central atom. In this case, the carbon atom is surrounded by two regions of electron , one for each double bond it forms with the sulfur atoms.

This means that its steric number will be equal to ##2##. The carbon atom will thus be ##"sp"## hybridized. It will use one s and one p orbitals to form the hybrids, and the remaining p-orbitals to form with the two sulfur atoms.

The will thus be linear, the basic ##"AX"_2## model.
