A polar molecule is characterized by the presence of opposite charged regions within the molecule, resulting from the unequal sharing of electrons between atoms. This usually occurs when atoms with different electronegativities form a bond, leading to one end of the molecule having a slight positive charge and the other end having a slight negative charge (dipole).
So, among the options provided:
-
Opposite Charged Regions: This is the correct answer because polar molecules have regions with partial positive and partial negative charges.
-
Antarctica: This does not relate to the definition of a polar molecule.
-
Temperature: Although temperature can affect molecular behavior, it does not define what makes a molecule polar.
In summary, the key characteristic that makes a molecule polar is the presence of opposite charged regions due to unequal electron sharing.
