1. Dopamine is a hormone and neurotransmitter that plays a role in motor control, motivation, and reward. NH2 HO OH dopamine a. Circle the alpha carbon(s) in dopamine. Is the leaving group bonded to this alpha carbon a good leaving group or poor leaving group? Give reasons. b. Box the atom that is the strongest base. Give the approximate pka (give a number) of the conjugate acid of this base. c. Consider the sequence of reactions: -NH2 3 HO A 2 HO OH HO OH dopamine B OH с (i) Determine reaction condition 1. Give the expanded formula. Identify the reaction type (acid-base, substitution, elimination, addition). (ii) Determine reaction condition 2. Give the expanded formula. Use curved arrows to show how this reaction occurs. (iii) Determine reaction condition 3. Give the expanded formula. (iv) Draw the structure of Compound C. Identify the reaction type (acid-base, substitution, elimination, addition).
