Question

3. See an electronegativity table. Compare C, H, O, and N. Rank these elements from the most electronegative to least In the structures in Questions 1a and 2c and 2e, circle the most polar bond. Box the atom with the partial positive charge. 4. 40,000 tons of acetaminophen are consumed per year. Misuse causes liver damage. Identify the functional groups in blue. (Me = methyl group-CH3-) OH 0 cytochrome P450 Me N in the body acetaminophen (Tylenol) NAPQI Toxic to liver Phenacetin is a carcinogen and damages kidneys; it was replaced by acetaminophen. Identify the functional groups in blue OH VS acetaminophen (Tylenol) Analgesi Analgesic 1887-1983 5. Valence Shell Electron Pair Repulsion (VSEPR) theory-the shape at a central atom is based on the number of bonding pairs and lone pairs surrounding a central atom Tetrahedral 4 bonds and 0 l.p Trigonal pyramid-3 bonds and 1 l.p Bent = 2 bonds and 2 lp. Trigonal planar = 3 bonds and 01.p a. For each compound in Question 1, determine the shape at each central atom using VSEPR theory b. Structure determines shape, shape determines polarity For each compound in Question 1, determine whether the compound is polar or non-polar

Explanation / Answer

Q3

electronegativity increaes as we go to the right of the periodic table

then

O > N > C > H

Q4.

acetaminophen ocntians:

-NH group = amine (secondary)

Benzene ring = aromatic

-OH compound = alochol (in blue, Acetaminophen)

C=O = compound is ketone (in NAPQI)
