MOLECULAR POLARITYFIELD NOTE 99 / 175
Is CS2 polar or nonpolar?
CS2 is a nonpolar molecule because its linear shape causes the two C=S bond dipoles to cancel, and the C–S electronegativity difference is nearly zero anyway.

Why CS2 is nonpolar
Carbon disulfide is linear like CO2, but the electronegativity difference between C (2.55) and S (2.58) is only 0.03 — essentially zero. Even without symmetry, the bonds would be nearly nonpolar.
What to notice
CS2 is symmetric like CO2. Carbon and sulfur also have very similar electronegativities, so its individual C–S bond dipoles are small.
Common questions about CS2
- 01
What does the Lewis structure of CS2 show?
The common structure is S=C=S. Carbon forms two double bonds, and each sulfur has two lone pairs.
- 02
What is the molecular geometry of CS2?
CS2 has a linear molecular geometry. The 3D model shows representative bond angles of 179.9°. These angles come from the displayed model coordinates.
- 03
What is the molar mass of CS2?
CS2 has an approximate molar mass of 76.13 g/mol, calculated from its formula using abridged standard atomic weights. Natural isotope variation can change the last digits.
