CHEM 245: Organic Chemistry Lab

Learn the steps to make a 2.5 L of 0.100 M KCl solution from a 5.5 M stock solution in this easy-to-follow tutorial.

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.

When water boils, bubbles rise to the surface, but what's in these bubbles? Let's evaluate the options. Option d, water vapor, is correct; the bubbles during boiling are primarily composed of water vapor, the gaseous state of water.

Learn how to find the density of silver using weight and water displacement. A step-by-step guide to a common laboratory technique.

This video provides insights into the concept of geometric isomerism in organic chemistry and explains why alkynes, which contain carbon-carbon triple bonds and adopt a linear structure, cannot exhibit this form of isomerism, unlike alkenes with double bonds that restrict rotation.

Join us as we explore the fascinating world of peptidyl transferase, one of the most conserved sequences in biology. In this video, we delve into the implications and draw intriguing conclusions from its exceptional conservation across species.
