Why is co2 linear and not bent. Compared to the SO2, theres a lone pair and there is one positive and one negative end. The central carbon atom has two electron domains (two double bonds and zero lone pairs), so both the electron geometry and molecular geometry are linear. This seeming contradiction is one of the most common points of confusion in chemistry, and the explanation comes down to molecular shape. Oct 23, 2023 · On the other hand, carbon dioxide (CO2) does not have a net dipole because it is a linear molecule. The two polar bonds in CO2 are equal and in opposite directions, so they cancel each other out. Explain how a molecule that contains polar bonds can be nonpolar. This is what makes of S O 2 a polar molecule because the dipole moments of both bonds of not cancel out, the molecule will have a net dipole moment. This gives it an arrangement of MX2, which correlates to a linear shape.
