Estrutura e ligação

Let's review the basics of chemical bonds including dot structures, hybridization, bond-line structures, electronegativity, and polarity. We will also discuss how bonding and intermolecular forces relate to physical properties such as boiling point.

Ressonância e reações ácido-base

Let's review how to keep track of electrons using formal charges, oxidation states, oxidation-reduction reactions, and resonance structures. We will also go over the principles of acid-base chemistry.

Alcanos, cicloalcanos e grupos funcionais

The properties of organic molecules depend on the structure, and knowing the names of organic compounds allow us to communicate with other chemists. We'll be learning about different aspects of molecular structure, including common functional groups and conformations.

Estereoquímica

Just like how your left foot doesn't quite fit your right shoe, molecules also can have properties that depend on their handedness! This property is called chirality. We will go over what makes a molecule chiral, stereoisomers, assigning configurations using the R,S system, optical activity and Fischer projections.

Reações de substituição e eliminação

Sn1, Sn2, E1, and E2 reactions form the basis for understanding why certain products are more likely to form than others. We will learn about the reaction mechanisms, and how nucleophilicity and electrophilicity can be used to choose between different reaction pathways.

Alcenos e alcinos

Alkenes and alkynes can be transformed into almost any other functional group you can name! We will review their nomenclature, and also learn about the vast possibility of reactions using alkenes and alkynes as starting materials.

Alcoóis, éteres, epóxidos, sulfetos

Alcohol and thiol groups are important functional groups for applications ranging from enzyme reactions to making flexible contact lenses. We will be reviewing naming oxygen and sulfur containing compounds. Then we will be ready to learn about some reactions that involve alcohols, ethers, epoxides, thiols, and sulfides as both reactants and products.

Sistemas conjugados e reações pericíclicas

Molecules with conjugation can undergo some interesting and useful reactions! We will be learning about the Diels-Alder reaction, including how to predict the stereochemistry and regiochemistry of the product based on the diene and dienophile.

Compostos aromáticos

The distinctive electronic structure of aromatic leads to some distinctive reactivity! We will be covering the naming of benzene derivatives, stability of aromatic compounds, electrophilic aromatic substitution, and nucleophilic aromatic substitution.

Aldeídos e cetonas

Aldehydes and ketones can be starting materials for a range of other functional groups. We will be learning about the nomenclature and reactions of aldehydes and ketones, including how to use acetals as protecting groups.

Ácidos carboxílicos e derivados

Did you know that many fruit aromas including banana (isoamyl acetate) and pineapple (ethyl butanoate) come from molecules containing ester groups? These compounds can be synthesized from carboxylic acids using a reaction called Fischer esterification. We will be covering naming carboxylic acids, as well as the diverse chemistry of carboxylic acid derivatives such as acid chlorides, amides, esters, and anhydrides.

Química do carbono alfa

The carbon that is one carbon away from an aldehyde or ketone group is the alpha carbon. The deceptively innocuous hydrogens bonded to the alpha carbon can be involved in some classic organic chemistry reactions such as aldol condensations. We will be learning about the formation of enolate anions, and how they can be used in Aldol condensations to build complex organic molecules.

Aminas

Amines are found in many biologically active molecules. Two examples are the charmingly named putrescine and cadaverine, which are formed by the breakdown of amino acids. We will be discussing the IUPAC nomenclature of amines.

Spectroscopy

Spectroscopy is the study of how light interacts with matter. We can use spectroscopy to determine the structure and functional groups in organic compounds. We will be learning about how to use IR, UV/Vis, and NMR spectroscopy.

Reações de substituição e eliminação

Sn1, Sn2, E1, and E2 reactions form the basis for understanding why certain products are more likely to form than others. We will learn about the reaction mechanisms, and how nucleophilicity and electrophilicity can be used to choose between different reaction pathways.
