ChemistrySingle correct+4 / -1Question 34 of 90

Molecule AB has a bond length of 1.617Å and a dipole moment of 0.38 D. The fractional charge on each atom (absolute magnitude) is : ( $e_0=4.802\times10^{-10}$ esu)

0.05

0.5

1.0

Answer and worked solution

Official answer: B

$\delta=\frac\mu{ed}=\frac{0.38\times10^{-18}}{4.802\times10^{-10}\times1.617\times10^{-8}}\approx0.05.$
