CHEM 2242: Organic Chemistry Laboratory

This video delves into the principles of gas behavior at standard temperature and pressure (STP) and how to determine the volume occupied by a given number of moles of gas under these conditions.

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.

Dive into the Kinetic Molecular Theory of Matter understanding how atoms and molecules possess kinetic energy which we measure as temperature. Explore the five core assumptions including the constant random motion of gas particles and the relation between kinetic energy and temperature. Demystify the concepts of particle collisions intermolecular interactions and the universal behavior of gases at given temperatures

Discover the process of determining a compound's molecular formula from its empirical formula and molar mass. Understand the calculations and reasoning behind deriving C?H? from the empirical formula CH? with a molar mass of 56.11 g/mol. Gain insight into fundamental chemistry concepts and computations.

Discover how to choose the right indicator for a titration involving Potassium hydrogen phthalate (KHP) and a strong base. Grasp the calculations from molar mass to pH and understand why Thymolphthalein is the ideal choice for a change near pH 8.95.

Discover the intricacies of atomic radius and its trends on the periodic table in this video. Unravel the factors influencing atomic size and explore how elements' positions on the periodic table affect their atomic radii.
