Based on electronegativity values, which bond has the highest degree of ionic character:
H--S


Si--Cl


Cs--Br?

  • chemistry - ,

    Ionic bonds tend to have an electronegativity difference ranging from 1.7-4.0. Looking on the periodic table, we can determine the ionic bonds.
    H--S
    2.2--2.58 (difference of 3.8)

    Si--Cl
    1.9--3.16 (difference of 1.26)

    Cs--Br
    0.79--2.96 (difference of 2.17)
    Therefore, it would be the Cesium and Bromine bond that would be the most ionic.
