And an ion is a discrete CHARGED particle, cationic or anionic.......of course, for every anion, there must be (somewhere!) a corresponding cation.....(why
Examples of ions include
The difference between a molecular ion and a free radical? Well, a molecular ion is a collection of atoms with a positive or negative charge, e.g.
Free radicals tend to be highly reactive species because they tend to pair up, and if they do so with a neutral species, they create another free radical that tends to continue the radical chain. Halogens are an excellent source of free radicals......as witness the reaction of halogen molecule under UV light......
And with species such as toluene, that can stabilize free radicals, we can get a radical chain of reactions.......
And the benzyl radical reacts with UNREACTED halogen........
And thus in the very act of reaction, a new halogen radical is delivered that continues the radical chain of reactions........
