9. Draw a molecular structure (skeletal or line drawing) for methyl acetate, \( \mathrm{CH}_{3} \mathrm{CO}_{2} \mathrm{CH}_{3} \), an ester molecule. 10. Draw a molecular structure (skeletal or line drawing) that contains a secondary \( \left(2^{\circ}\right) \) amine. 11. Consider the molecule donepezil (used to treat Alzheimer's disease). For the donepezil molecule below, encircle and label the following functional groups: Amine, Ketone, and Ether donepezil (used to treat Alzheimer's disease)
