Study Notes

Polar Molecules

  • A polar molecule is a molecule that has a permanent electric dipole moment, resulting from an uneven distribution of electrons within the molecule.

Characteristics of Polar Molecules

  • Polar molecules have a slightly positive charge on one end and a slightly negative charge on the other end.
  • This uneven distribution of electrons creates a permanent electric dipole moment.

Object that Can be Described as an Ion

  • An ion is a charged particle that can be formed when an atom gains or loses electrons.

Difference Between Polar and Non-Polar Molecules

  • Polar molecules have a permanent electric dipole moment, while non-polar molecules do not.
  • Non-polar molecules have a symmetrical shape, resulting in a uniform distribution of electrons.

Neutral Molecules

  • A neutral molecule is a molecule that does not have a permanent electric dipole moment.
  • Neutral molecules have a symmetrical shape, resulting in a uniform distribution of electrons.

Examples of Polar Molecules

  • Water (H2O) is an example of a polar molecule due to its bent shape, which results in an uneven distribution of electrons.

Importance of Polar Molecules

  • Polar molecules play a crucial role in many biological and chemical processes, as they are capable of forming hydrogen bonds and ionic bonds.

Note on Polar Molecules

  • The polarity of a molecule determines its ability to dissolve other substances and participate in chemical reactions.
