Bond Length and Ionic Character

Postby Serena Patel 2H » Thu Oct 27, 2016 8:27 pm

Could someone please explain what bond length/strength of the bond has to do with the molecule's ionic character? I'm a bit confused on this.

To be electronegative is to have a strong electron pulling power. When comparing bond lengths and ionic character, we can look at the trend that the greater the difference in electronegativity, the greater the ionic character. So, the more electronegative the bond, the shorter the bond length and the stronger the bond strength.

You can also think of it in terms of ionic and covalent bonds. The bigger the difference in electronegativity, the more ionic a bond is, the longer the bond length and the weaker the bond strength. This makes sense because we don't think of ionic compounds as sharing electrons and ionic compounds dissociate more easily in water.
