Neco Model Questions Vol1 2022 Chemistry Question 27
Practice objective / multiple choice question 27 from the 2022 Neco Model Questions Vol1 Chemistry examination.
A diatomic molecule AB has a measured bond length of 115 pm and a dipole moment of 0.60 D. The dipole moment is related to the electronegativity difference by \(\mu = 0.208\,\Delta\chi\,d\) where \(d\) is the bond length in ångströms. (i) Find the electronegativity difference \(\Delta\chi\) between A and B. (ii) If element A has a Pauling electronegativity of 1.0, determine the electronegativity of element B.
