CHE 13699: Intro Chemistry I

This discussion delves into the use of acetone as a solvent for removing water from laboratory glassware, exploring the science behind its effectiveness and the role of hydrogen bonding in facilitating rapid evaporation.

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.

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.

Unravel the science behind endothermic and exothermic processes by studying vaporization and condensation. Grasp the molecular changes involved and understand the role of heat in these transformations. A comprehensive look into why vaporization requires heat, while condensation releases it.

Uncover the science behind boiling points and molecular interactions in this video. Explore why Dimethylamine boils at a higher temperature than Trimethylamine, despite having a lower molecular weight, and gain insights into the role of molecular structures in determining physical properties.
