OH
Hey guys! Quick question? Is OH a radical? I was doing question 2C.1 and it said OH was not a radical in the answer key.

Re: OH
Ya it might seem like OH is a radical because if you add up the valence electrons to make the lewis structure it is 7e- (6e- from O and 1e- from H), which would leave one electron unpaired. However, OH exists as OH-, so a total of 8e- (6e- from O + 1e- from H + 1e-), making OH- not a radical.

Re: OH
A radical is a compound with unpaired electrons (does not fulfill octet rule). OH is a radical because it only has seven valence electrons, instead of eight.

Re: OH
OH- is not a radical. If we look at its molecular structure, the oxygen and hydrogen atoms are connected by a single bond, leaving 3 lone pairs around the oxygen atom. We know that O has 6 valence electrons and H has 1 valence electrons, making the total number of valence electrons for this molecule 8 if we include the extra electron as indicated by the -. When we count up all the electrons in the molecule, two in the bond and 6 surrounding the O atom, it equals 8, meaning there is not any extra electrons that would make OH- a radical.
