Radicals

Postby LNgo 1G » Thu Nov 07, 2019 6:52 pm

When drawing the Lewis structure for a radical molecule, how do you know which atom the single lone electron belongs to?

Typically radicals are formed by breaking bonds, so wherever the bond is broken is where the single lone electron will be. Other than that, I think they're usually placed at the central atom, such as in methyl and hydroxyl.

Hi LNgo 14A! I think it would make sense if the single electron was on the more electronegative atom. Because it's more electronegative, the atom will want to take as many electrons as possible and this single electron is no exception. I'm not sure, but I hope this helps explain it!

Are there atoms that commonly are radicals? Or can any atom be a radical?

This is more of an organic chemistry topic when you have to draw resonance structures regarding radical molecules. In orgo, the radical is most commonly found on the C, but in general, any atom can exhibit a radical. Radicals are notable when they appear on structures that should have their octet filled but are just one electron short - hence them being unstable and radical.

How do you know if something is a biradical molecule though? The adding valence electrons to get an odd number doesn't exactly work with biradicals right?
