Study Notes
Dipole Moment
- A dipole moment is a measure of the separation of positive and negative electric charge within a molecule.
- It is a vector quantity, represented by the symbol μ (mu), and is typically measured in Debye units (D).
Representation of Dipole Moment
- The dipole moment is represented by an arrow pointing from the positive charge to the negative charge.
- The length of the arrow is proportional to the magnitude of the dipole moment.
Dipole Moment in Different Molecules
- In a molecule with a centro-symmetric shape (e.g., CO2, CH4), the dipole moment is zero.
- In a molecule with a non-centro-symmetric shape (e.g., H2O, CO), the dipole moment is non-zero.
Implications of Non-Zero Dipole Moment
- A non-zero dipole moment indicates the presence of a permanent electric dipole in the molecule.
- This suggests that the molecule is polar, with a partial positive charge on one end and a partial negative charge on the other.
Factors Affecting Dipole Moment Magnitude
- The magnitude of a molecule's dipole moment is affected by the difference in electronegativity between atoms in the molecule.
- The bond length and angle also influence the dipole moment magnitude.
