Week 6 - Case Study: Chemical Structure of Neurotransmitters Acetylcholine is a neurotransmitter of the autonomic nervous system which sends information through the neurons to target organs. 1. ( 1pt ) Identify the circled functional group. Functional group: 2. ( 1pt ) Calculate the formal charge on the nitrogen of this structure. Show your work. 3. ( 5pt ) Draw the Newman projections for the different conformations obtained through 60 bond rotations around the CH2CH2 bond of this molecule. Abbreviate the two functional groups as OAc and NMe. ACH2 ACH5 ACH3 5. (1 pt) Identify which conformation is anti (circle one): 112345 6. (1 pt) Identify which conformation(s) are eclipsed (circle): 12345 7. (1 pt) Identify the most stable conformation(circle one): 12345
