Title: Which bond is more polar? Why?
Post by: ilc12girl09 on March 18, 2009, 04:28:36 PM
Hi! So ok, I'm doing grade 12 chem by myself and the question they are asking is: Which of these bonds is most polar amd which is least: S-O, Cl-Cl, or Cl-O? and it says to justify my answer, and I'm clueless! Help, please.

Thank you! :)

Dear ilc12girl09;

At least for a start:    http://www.ausetute.com.au/bondpola.html

Good Luck!

The S-O bond is most polar as O has comparatively higher electronegativity than Sulphur due to its smaller size.The Cl-Cl bond is the least polar.
Hence the order must be: S-O>Cl-O>Cl-Cl
