Polarity of Bonds and Molecules (CHEM 1405)
Back to Chemistry 1405 Practice Problems
|
Electronegativity difference determines the type of bond. < 0.3 nonpolar covalent bond > 0.3 but < 1.7 polar covalent bond > 1.7 ionic bond |
Electronegativities
hydrogen 2.1 calcium 1.0
sulfur 2.5 oxygen 3.5
nitrogen 3.0 iodine 2.5
silicon 1.8 chlorine 3.0
mercury 1.9 carbon 2.5
