Question
Which of the following species is a radical? A. CN− B. NO C. NO3− D. KrF+ E. SF6
Solution
The species that is a radical is B. NO. A radical is a molecule that contains an unpaired electron, and NO has 11 valence electrons, an odd number, which means one electron is unpaired. The other species (CN-, NO3-, KrF+, SF6) all have an even number of valence electrons, meaning they are not radicals.
