Radical Placement

Postby Cam Bear 2F » Wed Nov 08, 2017 3:00 pm

Hey guys! When there's a radical, how do you know which atom gets the unpaired electron? For instance on chapter 3 number 59a why do you place it on Cl as opposed to O?

Thanks!

The radical electron goes to the least electronegative atom.

How do we know that Cl has lower electronegativity than O?

Just based off the periodic trends, we see that going down a group electronegativity decreases and chlorine is lower than oxygen. Also, since the chlorine atom is larger than the oxygen atom, it will be less electronegative because the electrons will be farther away from the pull of the nucleus. Oxygen on the other hand is smaller and will more readily attract the electrons.
