Determine the most polar covalent bond among the given choices. Recall that a covalent bond is formed by the sharing of electrons by two non-metals.
Recall that for a covalent bond to be:
• Polar: electronegativity difference must be greater than 0.5
• Non-polar: electronegativity difference must be less than 0.5
The higher the electronegativity difference, the more polar a bond is. Using the provided electronegativity values, find the EN difference
Given the electronegativities below, which covalent single bond is most polar
Element: H C N O
Electronegativity: 2.1 2.5 3.0 3.5
