Question 2 0.75 / 1 pts Identify the circled functional groups in the given structure of L-Tyrosine, an amino acid that serves important functions in such diverse pathways as photosynthesis in plants and neurotransmission in humans. D B . NH2 HO1 A: Hydroxyl group B: Aromatic ring C: Amine D: Carboxylic acid Answer 1: Hydroxyl group Answer 2: Aromatic ring Answer 3: Amine Answer 4: Carboxylic Acid Question 3 0.75 / 1 pts The species shown below is known as a sulfonium ylide, and appears as an intermediate in a pathway known as the Swern reaction that converts an alcohol to an aldehyde or ketone. All lone pairs are shown explicitly and all atoms have complete octets, but formal charges have been left off. Given the structure, we can conclude that carbon number [Select] should bear a formal charge of [ Select , while the sulfur atom should have a formal charge of Select The curved arrow indicates the relationship between the given structure and a second Select] form, with the true electronic structure of the molecule best understood as a hybrid of these two canonical forms. 3 :0 S: R 1 2 Answer 1: 3 Answer 2: -1 Answer 3: +1 Answer 4: isomeric
