Choose the molecule or compound that exhibits dipole-dipole forces as its strongest intermolecular force. question 13 options: a. bcl3 b. n2 c. h2o d. so2 e. cbr4

The molecule that has dipole-dipole forces as the strongest intermolecular force is SO2.

A compound is formed from two or more atoms. The bond in a molecule could be polar of they have a large difference in electronegativity. In such case, we can say that the molecule is polar.

The polar molecules exhibit dipole-dipole forces. The molecule that has dipole-dipole forces as the strongest intermolecular force is SO2.

d. SO2. SO2 is a bent molecule, so the S-O bond dipoles so not cancel. The strongest intermolecular forces are dipole-dipole forces.

“a .BCl3” is incorrect. BCl3 has B-Cl bond dipoles, but they point to the corners of an equilateral triangle. The molecular symmetry causes the bond dipoles to cancel. The strongest intermolecular forces are the weak London dispersion forces.

“c. H2O” is incorrect. The molecule has hydrogen bonds, which are stronger than dipole-dipole forces.

“e. CBr4” is incorrect. CBr4 has C-Br bond dipoles, but they point to the corners of a regular tetrahedron. The molecular symmetry causes the bond dipoles to cancel. The strongest intermolecular forces are the weak London dispersion forces.
