Oct 17, 2019 · Carbon dioxide (CO2) is nonpolar because it has a linear, symmetrical structure, with 2 oxygen atoms of equal electronegativity pulling the electron density from carbon at an angle of 180 degrees from either direction. Polarity in a molecule occurs due to the unequal sharing
Trigonal planar: triangular and in one plane, with bond angles of 120°. Tetrahedral: four bonds on one central atom with bond angles of 109.5°. Trigonal bipyramidal: five atoms around the central atom; three in a plane with bond angles of 120° and two on opposite ends of the molecule.
