Which statement describes the strength of dipole-dipole intermolecular forces?

dipole-dipole forces are the weakest intermolecular force.
dipole-dipole forces are the strongest intermolecular force.
dipole-dipole forces are medium-strength intermolecular forces.
dipole-dipole forces are equal to the force between atoms within the molecule.

Amines are good nucleophiles, even though they are neutral molecules. how would the rate of an sn2 reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? amines are good nucleophiles, even though they are neutral molecules. how would the rate of an reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? because both reactants in the rate-limiting step are neutral, the reaction will be faster if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will be slower if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will occur at the same rate if the polarity of the solvent is increased. request answer
