The dipole moment is calculated as the product of the charge and the bond length. Which of the following statements is accurate?

1. The dipole moment of AB molecules is 4.8 × 10^-10 × 2.82 × 10^-8 = 13.53D.
2. The dipole moment of CD molecules is 4.8 × 10^-10 × 2.67 × 10^-10 = 12.81D.
3. The percentage ionic character is given by the formula: (Measured dipole moment of the bond / Dipole moment of a fully ionic bond) × 100.
4. None of these statements are correct.

Correct answer: The percentage ionic character is given by the formula: (Measured dipole moment of the bond / Dipole moment of a fully ionic bond) × 100.

Solution

Option C correctly describes the formula for calculating the percentage ionic character of a bond, which is a standard concept in dipole moment analysis.
