Q:

Is CS2 polar or non-polar?

A:

Quick Answer

Carbon disulfide (CS2) is a nonpolar, linear molecule. Carbon forms slightly polar bonds with sulfur, but due to the symmetrical arrangement of the bonds, the polarities cancel out.

Full Answer

Carbon disulfide is a linear molecule, with carbon at the center. Carbon forms double bonds with each of the sulfur atoms. Since sulfur is slightly more electronegative than carbon and has a stronger attractive force on the bonded electron pairs, the electrons are unequally shared, giving the sulfur atoms a partial negative charge. This causes the bonds on each side of carbon to be slightly polar.

The bonds are arranged at a 180-degree angle (linear) around the carbon atom. Due to the symmetrical arrangement of the bonds and the partial negative atoms, the polarities of the bonds cancel out, making the molecule nonpolar.
