Radicals

Postby Milena Aragon 2B » Sun Nov 25, 2018 8:50 pm

Does it matter where the unpaired electron is placed in a molecule? There was a question (focus 2.61 -7th edition) that asked whether HOCO was a radical and why so I placed the unpaired electron on the oxygen and gave carbon its octet but the solutions manual said that it was a radical because carbon had an unpaired electron. Wouldn't the molecule be more stable if O had the unpaired electron?

From what I remember, my TA said it shouldn't matter for this class. Just place the unpaired electron in a way that the formal charge is as close to 0 as possible.

I believe that a single unpaired electron goes to the oxygen because it is more electronegative than the carbon. The carbon then becomes the radical and, if it is surrounded by a single unpaired electron, a single bond, and a double bond, it has a formal charge of zero.
