Radical ✏ Chemistry In a Nutshell




1. What are Radicals?

  • Radicals are molecules or atoms with at least one unpaired electron.
  • They usually form when a normal electron pair bond breaks, leaving one electron unpaired.
  • Most molecules have an even number of electrons, but radicals are exceptions.


2. Example of a Radical

  • NO₂ (Nitrogen Dioxide)
    • Nitrogen has an unpaired electron due to its low electronegativity.
    • This makes NO₂ a radical and highly reactive.
    • It does not fulfill the octet rule, meaning it has an incomplete octet.


In a nutshell

  • Highly reactive due to their unpaired electrons.
  • Can participate in chain reactions (e.g., in combustion and polymerization).
  • Play a role in biological processes (e.g., free radicals in the human body can cause cell damage).

"Radicals are Restless!"

  • They have unpaired electrons.
  • They are highly reactive.
  • They don’t always follow the octet rule.
