OCHEM 8A: lecture 1

LSS tutoring

Support provided by tutors, specifically Sean and Kelis in this context.

Organic Chemistry Learning Center

The designated space for group office hours and study sessions.

Inclusive Access

A system that allows students to access course materials through an online platform without needing separate codes or logins.

Valence Electrons

Electrons in the outermost shell of an atom that are involved in forming bonds.

Formal Charge

A theoretical charge assigned to an atom in a molecule, calculated by comparing valence electrons to associated electrons.

Lewis Structure

A diagram that shows the bonding between atoms and the lone pairs of electrons in a molecule.

Electronegativity

The tendency of an atom to attract electrons in a bond.

Octet Rule

The principle that atoms tend to bond in such a way that they have eight electrons in their valence shell.

Covalent Bond

A chemical bond that involves the sharing of electron pairs between atoms.

Isotope

Atoms of the same element with the same number of protons but different numbers of neutrons.

Resonance Structures

Different Lewis structures for the same molecule that show the distribution of electrons.

Polarity

A property of molecules having a partial positive charge on one side and a partial negative charge on the other.

Hybridization

The concept of mixing atomic orbitals to form new hybrid orbitals for bonding.

Functional Groups

Specific group of atoms within a molecule that are responsible for its characteristic reactions.

Chemical Reaction

A process that involves the rearrangement of the molecular or ionic structure of a substance.

Periodic Table

A tabular arrangement of the chemical elements organized by atomic number, electron configuration, and recurring chemical properties.

Structural Formula

A graphic representation of the molecular structure indicating how the atoms are arranged.

Polyatomic Ions

Ions that consist of more than one atom.

Molecular Geometry

The three-dimensional arrangement of atoms in a molecule.

Hydrogen Bonding

A weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other.

Nomenclature

The system of naming chemical compounds.

Electrolyte

A substance that dissociates into ions in solution and acquires the capacity to conduct electricity.

Kinetics

The study of the rate at which chemical processes occur.
