Question

Order the following compounds according to the decreasing ionic character of their bonds: CCl4 , BaCl2 , TiCl3 , ClO2 .

Answer 1

------- decreasing ionic character ------>

BaCl2 ..... TiCl3 ....... CCl4 ...... Cl2O

Explanation:

Ionic character is determined from the electronegativity difference, ΔEN.  The greater is ΔEN, the greater is the percent ionic character.

------- decreasing ionic character ------>

BaCl2 ..... TiCl3 ....... CCl4 ...... Cl2O

72% ........ 48% ....... 9% ..........2%
