Polar molecules tend to be ________.

Question

Quizplus · Accepted Answer

Polar molecules have an uneven distribution of electrons, which leads to a partial positive end and a partial negative end. This occurs when the molecule is asymmetrical. Therefore, choice C is the best option. Symmetrical molecules, such as diatomic molecules, would not have this uneven distribution of electrons and are thus not polar. Choice A is incorrect because symmetrical molecules are not polar. Choice B is also incorrect because elongation alone does not necessarily imply polarity.
