Radicals And Biradicals

Postby Maldonado3K » Sun Oct 29, 2017 11:55 pm

Simply definition of radicals and biradicals and the difference between them? What do we have to know about them and what connections does it have with finding Lewis structures?

Hi there,

A radical is a compound with one unpaired electron. A biradical is a compound with two unpaired electrons. Pictures attached for comparison, one dot represents an unpaired electron.

It is important to know that two radicals can come together and form a bond between each unpaired electron, forming a bond with paired electrons.

Radicals and Biradicals are extremely reactive and generally don't last very long in nature- for example, methyl on its own is so unstable that it cannot be stored.
