Question

The strongest intermolecular force that exists in the following molecule is? o=c=o

a. LDF's

B. dipole-dipole

C. Hydrogen Bonding

D. Covalent bonding

Answer 1

The only intermolecular forces present in CO2 are Van der Waals . Explanation: ... All atoms and molecules have Van der Waals forces, so these are present in CO2 . The next strongest are permanent dipole-dipole interactions, which are present between polar molecules.

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.
