- Shown below is Streptomycin, and Neomycin B. Circle and label as many functional groups in these molecules as you can. a. Label each chiral carbon in Streptomycin. How many total stereoisomers exist for Streptomycin? b. Label each chiral carbon in Neomycin B. How many total stereoisomers exist for Neomycin B?For Tylenol (Acetaminophen), what is the primary and secondary carbon? Any enantiomers? (R and S)A researcher conducted an experiment and needed to use L-Leucine. He is able to scavenge four bottles that have faded labels and impossible to identify which enantiomer of leucine or isoleucine it contains. The researcher remembers his melting point lab and decides to classify the identity of the compounds based on the melting point. He experimentally determines a melting point for each bottle: (see table or image attached)i. 291-295 °Cii. 283-287 °C iii. 289-291 °C iv. 292-294 °C Which of the following bottles is L-Leucine?
