CHEM 2311: Organic Chemistry I

In this video, we explore the information that knowledge of the number of protons in a neutral element's atom can provide. Options for determining neutron count, electron count, and identifying the element's name are examined, with a conclusion that it allows us to know both the number of electrons and the element's name.

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.

This discussion revolves around the classification of chemical bonds as ionic, polar covalent, or covalent based on the electronegativity difference between the atoms involved. The general criteria for this classification are explained: a difference greater than 1.7 indicates an ionic bond, between 0.5 and 1.7 signifies a polar covalent bond, and less than 0.5 designates a covalent bond. It then applies these criteria to four specific examples, including the CC bond in ethane (H?CCH?), the KI bo
