For each compound below, draw in all missing lone pairs and indicate whether each lone pair is delocalized or localized. Then, use that information to determine the hybridization state for each atom that has a lone pair. Hint: allylic lone pairs are delocalized and do not count towards the steric number.
Much of Earth's history can be unraveled studying sulfur. Sulfur can be used as "geothermometer". The ratios of stable sulfur isotopes change with the temperature of Earth's processes. For example, igneous systems deep inside the Earth occur at very high temperatures, hydrothermal systems occur at intermediate conditions, and sedimentary rock weathering occurs at low temperatures. The composition of stable sulfur isotopes varies across the 1000 degree temperature range. 10. How many peaks would be seen in the mass spectra for such a study? Make a basic sketch (bar chart) a.m.u. vs % natural abundance and label each peak's a.m.u. and % natural abundance.
