CHM 221: Organic Chemistry I

Unlock the world of chemical formulas and their atom ratios. Learn to write compounds like CaI?, N?O?, SiO?, and ZnCl? in this chemistry tutorial.

Master metric unit conversions with step-by-step examples, including cm to meters, g to kilograms, cm to millimeters, and mL to liters.

Explore the protonation of amino acids, specifically valine and threonine, when subjected to a pH lower than their isoelectric points, highlighting the structural changes in their carboxyl and amino groups.

Learn the process of determining the density of a rectangular metal bar using its measurements. Understand how volume and mass play a crucial role in the calculation, and the importance of representing results with the correct number of significant figures

Discover the analysis of ionic character in compounds based on electronegativity differences. Learn about the contrasts between NaBr vs. HBr and BrCl vs. FCl. Grasp why NaBr and FCl showcase greater ionic character than their paired compounds.

We explore Lewis structures, which depict atom bonding and lone electron pairs. We create Lewis structures for potassium, barium, aluminum, and bromine by using group numbers in the periodic table to determine their valence electrons.
