According to the Pauling scale, Oxygen has an electronegativity of 3.5 and Hydrogen has 2.1. What is the numerical difference that determines water's polarity?
Q1. According to the Pauling scale, Oxygen has an electronegativity of 3.5 and Hydrogen has 2.1. What is the numerical difference that determines water's polarity?
Answer: 1.4
Explanation: The electronegativity difference is 3.5 - 2.1 = 1.4. 0.9 is the difference for C-H bonds, not O-H bonds.
