Igcse Model Questions Vol1 2019 Chemistry Question 17
Practice objective / multiple choice question 17 from the 2019 Igcse Model Questions Vol1 Chemistry examination.
A diatomic molecule AB has a measured dipole moment of 2.5 D and an internuclear distance of 120 pm. (1 D = 3.336 × 10⁻³⁰ C·m.) Assuming the dipole arises from a separation of partial charges ±q, calculate the effective charge q and decide whether the bond is polar covalent or ionic. Treat a bond as ionic if \(q > 0.5\,e\), where \(e = 1.602\times10^{-19}\) C.
