Which of the following statements describes a polar molecule?
because electrons are transferred between atoms, the molecule conducts electricity
electrons are equally shared between atoms, giving them a negative charge
the molecule has unequal sharing of electrons, atoms have slightly positive or negative charge
a polar molecule is perfectly symmetrical, electrons travel freely around atoms

Why are ion-dipole interactions stronger than dipole-dipole interactions?
Because ions have a complete charge while dipoles only have partial charges
Because ion-dipole interactions only occur in aqueous solutions
Because dipole-dipole interactions are temporary
Because ions are smaller than molecules
