Question

Which of the following correctly describes a polar molecule?

a. a molecule where there are equal pulls in all directions.
b. a molecule where there is a stronger pull on electrons in a specific direction.
c. a molecule that loses electrons and becomes negatively charged.
d. a molecule that gains electrons and becomes positively charged.

Answer 1

A polar molecule is one with an unequal distribution of charges, resulting in one end being slightly positive and the other slightly negative, as in the case of water.

Step-by-step explanation:

The correct description of a polar molecule is a molecule where there is a stronger pull on electrons in a specific direction. This occurs due to an asymmetrical distribution of positive and negative charge within the molecule, leading to one end being slightly positive and the other end slightly negative. Such molecules include water (H2O), where the electrons are more attracted to the oxygen atom, resulting in a partial negative charge at the oxygen end and a partial positive charge at the hydrogen ends. This separation of charges makes the molecule polarized and capable of dipole-dipole interactions.
