What is the best way to determine where the radical will be placed?

A radical is defined as a molecule (or atom) with at least one unpaired electron. The methyl group is an example of a radical. Though the central carbon atom in the methyl group is able to form four bonds, only three hydrogen atoms bond with it, leaving it with one unpaired valence electron.

Determining which atom in a radical molecule contains an unpaired valence electron involves comparing the number of bonds an atom can make versus the number it actually makes. Since hydrogen can only form one bond, it is never the carrier of an unpaired valence electron in a molecule. Since carbon can form four bonds, it is often the carrier of the unpaired valence electron. Generally, the atoms that can't be the carrier in a radical molecule are those that can only form a single bond.

I hope this helped!

Give an octet to the atoms with higher electronegativity and less than an octet (radical) on the atom with lower electronegativity. There were assigned homework problems dealing with this.
