14. Alex needs to isolate pure acetylferrocene from a mixture of ferrocene, acetylferrocene, and diacetylferrocene. Checking the TLC and using 50% heptane and 50% ethyl acetate as the solvent, Alex finds that the Rf values are 0.9, 0.3, 0.1 for ferrocene, acetylferrocene, and diacetylferrocene, respectively. When Alex begins the eluting a column chromatography using pure heptane as the solvent, he begins collecting After collecting the heptane fraction, Alex switches to using 50% heptane and 50% ethyl acetate and observes two bands slowly moving down the column and separating on their way down. The first of these two bands Alex will collect is and the final band is 15. Alex is synthesizing wintergreen oil (methyl salicylate) by sulfuric acid catalyzed esterification of salicylic acid with methanol using a 1:1 mol ratio of acid and alcohol. After refluxing the mixture and checking '¹H-NMR after 45 1 hours and then again after 1 day, Alex finds that the ratio of how Alex

CONCLUSIONS: In general, the boiling points of compounds increase down a group in the periodic table. The melting points and boiling points for the hydrogen compounds of group 6A elements are in the table below. Melting Point (°C) Boiling Point (°C) H₂O 0.0 100.0 H₂S -82.0 -60.0 H₂Se -65.7 -41.2 H₂Te -49.0 -2.2 Use your understanding of chemistry to propose an explanation for the anomaly in the trend for the hydrogen compounds of group 6A elements shown in the table.
