Which of the following is the best explanation that CO2 is a non-polar...
CO2 is a non-polar molecule primarily because the dipole moment is zero.
In a molecule, a dipole moment is formed when there is a difference in electronegativity between the atoms. This causes a charge imbalance and creates a dipole (two poles, one positive and one negative). In CO2, the molecule is linear with the oxygen atoms on either side of the carbon atom. While oxygen is more electronegative than carbon, causing each C-O bond to be polar, the linear shape of the molecule ensures that the individual bond dipoles cancel each other out.
Because the molecule is symmetrical, the dipoles on either side of the carbon atom are equal in magnitude but opposite in direction. As a result, the net dipole moment of the entire molecule is zero, making it non-polar.
So, while the linear geometry (option A) and Sp hybridization (option C) contribute to the overall characteristics of CO2, the best explanation for its non-polarity is the zero dipole moment (option B).
