You have been given a solid with a melting range 142-148°C, and you attempt to recrystallize it from isopropanol (propan-2-ol). What type of melting range might you expect if the recrystallization were successful? The melting range would be higher, but about the same breadth O The melting range would be narrower and lower The melting range would be higher and broader The melting range would be broader but otherwise unchanged The melting range would be both higher and narrower

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.
