Correct Answer: D.The polarity of a molecule is dependent on its 3-D structure
A molecule’s dipole is an electric dipole with an inherent electric field (not be confused with a magnetic dipole which generates a magnetic field). Molecules can have dipole moments due to non-uniform distributions of positive and negative charges on the various atoms. For diatomic molecules there is only one (single or multiple) bond so the bond dipole moment is the molecular dipole moment, with typical values in the range of 0 to 11 D. For polyatomic molecules there is more than one bond, and the total molecular dipole moment may be approximated as the vector sum of all individual bond dipole moments.

The Dental Admission Test (DAT) is a test administered by the American Dental Association (ADA). The test is four hours and 30 minutes long and contains four sections. The test is designed to assess your knowledge in: biology, chemistry, organic chemistry, perceptual ability, reading comprehension, and basic math.
How Should I Study?
The DAT is the final challenge before you apply to dental school and should not be taken lightly. Depending on the strength of your scientific knowledge, your study schedule should be between 4 to 10 weeks. Here's a link to my definitive DAT study guide and schedule which will help you prepare.
Register for the DAT.
You should plan on taking the DAT late spring or during the summer of your application year. For example, the class of 2020 should take the DAT in the spring or summer of 2015. You can begin the registration process for the DAT at the ADA's website. Be sure to apply for a test date early as the registration process may take some time.
