Which of the following species are radicals? (a)NO2- (b) CH3 (c) OH (d)CH2O

What are radicals again? How do we determine them?

According to the textbook, "Species having electrons with unpaired spins are called radicals." You can determine whether a molecule is a radical by drawing out the Lewis structure I think. The dot next to the molecule represents the unpaired spin.

Why is d.) not a radical since Br has 7 valence e- and O has 6 valence e- for an odd total of 13e-?

BrO IS a radical because it has an odd number of valence electrons, but I think you are confusing #55 and #56 as part D for #55 is not BrO and that is instead part D for #56. Hope that helps! :)

Anytime a compound or molecule has an odd number of electrons its going to be a radical

The radical also normally goes on the central atom.
