Question

Identify the inorganic and organic free radicals.

• A. $\stackrel{\bullet }{O}H$, $\stackrel{\bullet }{C}{H}_3$
  
• B. $\stackrel{\bullet }{S}{O}_2$, $\stackrel{\bullet }{N}{O}_2$
  
• C. Both A and B
• D. None of these

Answer 1

Answer: (C)

Both A and B

In chemistry, a radical (more precisely, a free radical) is an atom, molecule, or ion that has unpaired valence electrons. With some exceptions, these unpaired electrons make free radicals highly chemically reactive towards other substances, or even towards themselves: their molecules will often spontaneously dimerize or polymerize if they come in contact with each other.

$\stackrel{\bullet }{C}{H}_3$ is an organic free radical, while $\stackrel{\bullet }{N}{O}_2,\stackrel{\bullet }{S}{O}_2,\stackrel{\bullet }{O}H$ are inorganic free radicals.

Hence, option C is the correct answer.
