Identifying Radicals

Postby Keon Amirazodi 3H » Wed Nov 18, 2020 3:48 pm

Is it true that a quick way to identify radicals without drawing Lewis structures is by just seeing if the molecule has an even or odd number of valence electrons? Does this work all the time?

Hi, and yes! Since bonds or lone pairs both have to have two electrons, all molecules that aren't radicals have to have an even number of electrons.

Hi!
Yes, all molecules that have an odd number of electrons are radicals.

Hi! I'm pretty sure that this is a good and quick way to identify if there is a radical but it is always safer to draw out the Lewis Structure just incase. Hope this helps!
