What would be the radicals shown?

LenalehmannnByLenalehmannn

hello everyone,

It's about radicals with IUPAC-compliant names and their order according to their stability. However, I haven't been able to identify all of them. Or rather, I'm unsure, especially since there are six radicals shown and I have 12 names available.

I would be grateful for any help!

My notes:

(from left to right)

1st column is acetyl

3rd column is methyl

5th column is phenyl

6th column is benzyl

order from stable to unstable:

benzyl radical (stabilization by mesomery) > tert-butyl radical (stabilization by hyperconjugation) > sec-propylradic (stabilization by hyperconjugation) > ethylradic > methylradic > phenylradic

  1. Column is isobutyl, column 2 is ethyl, column 4 is isopropyl.

Thank you. The rest is right? The stability of weak to stable would then be: methyl, ethyl, isopropyl, isobutyl, phenyl and benzyl. I am very insecure because I do not know exactly how to fix stability. I have now counted the carbon atoms.

I don't see an isobutyl radical.
