A flavor chemist attempted to isolate and identify the major flavor component of a recently discovered wild berry. A sample of berries was pureed in a blender , and the resulting slurry was dissolved in ethyl acetate. The solution was first extracted with 0.1 M HCI, followed by extractions with aqueous sodium bicarbonate. The ethyl acetate portion was concentrated and thin layer chromatography of the resulting oil indicated two compounds. Compound 1 with Rf of 0.2, and Compound 2 with an Rf of 0.6. The two compounds were separated by column chromatography, and the top spot (Compound 2) was identified as the essential oil. Compound 2 had the following physical characteristics: Formula: C11H1403 IR: 3100, 2950, 1735, 800 cm-1 1H NMR: 7.5 ppm, multiplet, 4H 4.5 ppm, septet, 1H 2.1 ppm, singlet, 3H 1.4 ppm, doublet, 6H The extraction with 0.1 M HCI would remove what type of compound from the ethyl acetate solution? O A. amides O B. amines O C. esters O D. alkenes

PROVISIONAL LEWIS STRUCTURES T01/S01 For each provisional structure, identify if it is the correct Lewis structure (C) or if it needs to be modified according to procedure MA or MB to obtain the correct Lewis structure. MA. Form multiple bonds to the central atom using lone pair on the terminal atom(s) until the central atom has an octet (or septet). MB. Form multiple bonds to the central atom using lone pair on the terminal atom(s) until the central atom has a formal charge of zero (0) or until two double bonds are formed. A provisional structure has the valence electrons distributed in order as (1) a bond between each pair of atoms, (2) an octet for each ligand (terminal) atom or ligand group (CH3, NH2 or OH) and (3) any remaining electrons on the central atom.
