Polarity of a molecule is expressed in terms of:
Correct answer: C. Dipole moment
- A. Bond strength
- B. Bond length
- C. Dipole moment
- D. Shape
Explanation
The polarity of a molecule is expressed in terms of its dipole moment. The dipole moment is a measure of the overall electrical charge separation within a molecule and its orientation. It indicates the degree of polarity in the molecule. A molecule is considered polar if it has a net dipole moment, meaning that there is an uneven distribution of electrons that results in a partial positive charge on one end of the molecule and a partial negative charge on the other end. This creates a separation of charge, or a "dipole," within the molecule.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
