Chemistry · CHEMICAL BONDING AND MOLECULAR STRUCTURE
हिन्दीA hypothetical diatomic molecule \( \text{A}-\text{B} \) has an experimental dipole moment of \( 1.20\text{ D} \) and a bond length of \( 1.50 \times 10^{-10}\text{ m} \). What is the percentage ionic character of the \( \text{A}-\text{B} \) bond? (Use \( 1\text{ D} = 3.336 \times 10^{-30}\text{ C m} \), \( e = 1.602 \times 10^{-19}\text{ C} \))

Correct answer · Option D
\( 16.7\% \)
Explanation
\( \mu_{\text{calc}} = e \times d = 1.602 \times 10^{-19} \times 1.50 \times 10^{-10} = 2.403 \times 10^{-29}\text{ C m} \). \( \mu_{\text{exp}} = 1.20 \times 3.336 \times 10^{-30} = 4.003 \times 10^{-30}\text{ C m} \). \( \%\text{ ionic} = \frac{4.003 \times 10^{-30}}{2.403 \times 10^{-29}} \times 100\% \approx 16.66\% \approx 16.7\% \).
