Sequence of Increasing Chemical Bond Polarity

The sequence of increasing chemical bond polarity can be determined based on the electronegativities of the elements involved in the chemical compounds.

1) K2O: Potassium oxide (K2O) is composed of potassium (K) and oxygen (O). Potassium has an electronegativity of 0.82, and oxygen has an electronegativity of 3.44. Therefore, the electronegativity difference is 3.44 - 0.82 = 2.62.

2) MgO: Magnesium oxide (MgO) consists of magnesium (Mg) and oxygen (O). Magnesium has an electronegativity of 1.31, and oxygen has an electronegativity of 3.44. The electronegativity difference is 3.44 - 1.31 = 2.13.

3) CaO: Calcium oxide (CaO) is formed by calcium (Ca) and oxygen (O). Calcium has an electronegativity of 1.00, and oxygen has an electronegativity of 3.44. The electronegativity difference is 3.44 - 1.00 = 2.44.

4) SO3: Sulfur trioxide (SO3) contains sulfur (S) and oxygen (O). Sulfur has an electronegativity of 2.58, and oxygen has an electronegativity of 3.44. The electronegativity difference is 3.44 - 2.58 = 0.86.

5) Al2O3: Aluminum oxide (Al2O3) is composed of aluminum (Al) and oxygen (O). Aluminum has an electronegativity of 1.61, and oxygen has an electronegativity of 3.44. The electronegativity difference is 3.44 - 1.61 = 1.83.

Therefore, the sequence of increasing chemical bond polarity is as follows: K2O < MgO < CaO < Al2O3 < SO3
