Incomplete Octet Vs Radical

Postby RahilVaknalliDis3A » Mon Nov 06, 2017 12:12 pm

Based on the Lewis structure of a molecule, how do you differentiate between those that are radicals and those that have an incomplete octet?

A radical is when a compound has an unpaired electron. So, in a Lewis Structure, you would have just one dot representing an unpaired electron instead of the usual two representing paired electrons. But with an incomplete octet a element can exist in a stable compound without the usual 8 electrons. For example, Beryllium has an incomplete octet and is stable with just 4 valence electrons.

Hope this helps!

Similarly, radical molecules will have an odd # of electrons. Make sure to count the charge, too!
