Is CO2 Polar or Non-Polar? To determine whether carbon dioxide (CO2) is polar or non-polar, we need to examine its molecular structure, electronegativity of the atoms, and overall symmetry. Step 1: Understanding Molecular Geometry CO2 has a linear molecular geometry. The central atom, carbon (C), is bonded to two oxygen (O) atoms. The bond angle is 180 degrees. Step 2: Electronegativity Values The electronegativity values for the relevant atoms are: Carbon (C): 2.55 Oxygen (O): 3.44 Step 3: Analyzing Bond Polarities To find out if the C=O bonds are polar, we calculate the difference in electronegativity: A difference of 0.89 indicates that the C=O bond is polar. Step 4: Overall Molecular Polarity Since CO2 is linear, the dipoles created by each C=O bond point in opposite directions. The two polar bonds effectively cancel each other out due to the symmetrical arrangement. Conclusion Because of its symmetric linear geometry and the cancellation of dipole moments, CO2 is classified as a non-polar molecule.
