CHE 230 F2019 Assignment 10 Student Name: ID Number: 10.W2S-1 Resonance structures of radicals: Draw two additional resonance structures for the molecule shown below. Be sure to show the curved arrows that demonstrate how you get from one resonance structure to the next. There should NOT be formation of partial charges in you structures. •H .U-I 10.W2S-2 When discussing radical reaction mechanisms we are concerned with bond strengths to make these mechanistic arguments. Which CH bond is the weakest in the molecule below? (c) (d) (b)HHHHH нхғн YY ILF (a) H3C (a) (b) (c) (d) 10.W2S-3 Provide a mechanism for the reaction in the desired spaces below.
