Biosynthesis of adreneline (epinephrine) 5. \( \begin{array}{lll}\mathbf{a}=\text { Proton transfer } & \mathbf{e}=\text { Electrophilic addition } & \mathbf{h}=\mathrm{S}_{\mathrm{N}} 1 \text { Nucleophilic substitution } \\ \mathbf{b}=\text { Lewis acid/base } & \mathbf{f}=\text { E1 Elimination } & \mathbf{i}=\mathrm{S}_{\mathrm{N} 2} \text { Nucleophilic substitution } \\ \mathbf{c}=\text { Radical chain substitution } & \mathbf{g}=\text { E2 Elimination } & \mathbf{j}=\text { Electrophilic aromatic substitution } \\ \mathbf{d}=\text { Radical chain addition } & & \end{array} \) Identify the mechanism by which each of the reactions above proceeds from among the mechanisms listed. Use the letters \( \mathbf{a} \mathbf{-} \mathbf{j} \) for your answers. 1. 2. Identify the mechanism by which each of the reactions above proceeds from among the mechanisms listed. Use the letters \( \mathbf{a} \) - j for your answers. 1. 2. 1. 5. \( \begin{array}{lll}\mathbf{a}=\text { Proton transfer } & \mathbf{e}=\text { Electrophilic addition } & \mathbf{h}=\mathrm{S}_{\mathrm{N}} \text { 1 Nucleophilic substitution } \\ \mathbf{b}=\text { Lewis acid/base } & \mathbf{f}=\text { E1 Elimination } & \mathbf{i}=\mathrm{S}_{\mathrm{N}} \text { 2 Nucleophilic substitution } \\ \mathbf{c}=\text { Radical chain substitution } & \mathbf{g}=\text { E2 Elimination } & \mathbf{j}=\text { Electrophilic aromatic substitution } \\ \mathbf{d}=\text { Radical chain addition } & & \end{array} \) Identify the mechanism by which each of the reactions above proceeds from among the mechanisms listed.
