What type of intermolecular force of attraction is found in co2?
Carbon Dioxide (
CO₂ is a linear molecule. The O-C-O bond angle is 180°.
Since O is more electronegative than C, the C-O bond is polar with the negative end pointing toward the O.
CO has two C-O bonds. The dipoles point in opposite directions, so they cancel each other out.
Thus, although CO₂ has polar bonds, it is a nonpolar molecule. Therefore, the only intermolecular forces are London dispersion forces.
