Because they contain an unpaired electron, free radicals are:

  1. Chemically inactive
  2. Chemically reactive
  3. Cations
  4. Anions

Correct answer: Chemically reactive

Solution

A free radical has an unpaired electron and no net charge (so it is neither a cation nor an anion). The unpaired electron makes radicals highly reactive, as they readily abstract atoms or add to other species to complete their electron pairing.
