Study Notes
Structure and Bonding
- Electron configuration and orbital diagrams are essential for understanding atoms, cations, and anions.
- Polarity of bonds and molecules depends on electronegativity and dipole moment.
- Formal charge, octet rule, and counting lone pairs on an atom are crucial for understanding bonding.
- Shape of molecules and hybridization are essential for writing bonding schemes.
- Intra- and intermolecular forces are important for understanding molecular interactions.
Drawing Structures
- Condensed structures can be converted to line bond (skeletal) structures.
- Line bond structures can be converted to condensed structures.
- Determining molecular formulas involves identifying and counting 1o, 2o, and 3o carbons and hydrogens, O, N, halides (Cl, Br).
- Alcohols can be classified as primary, secondary, and tertiary, noting that phenols do not belong to these classes.
Functional Groups
- Identifying functional groups includes alkenes, alcohols, aldehydes, ketones, carboxylic acids, esters, ethers, amines, amides, thiol, disulfides, and nitriles from given structures.
Reactions and Naming Compounds
- Types of reactions include acid-base reactions.
- Naming compounds involves naming alkanes, alkenes, alcohols (aldehydes, ketones, esters, carboxylic acids, etc.).
- Isomers can be structural (constitutional) and geometric (cis-trans) in alkenes and cyclic alkanes.
- Naming cyclo compounds involves recognizing specific structures.
Properties of Compounds
- Solubility of hydrocarbons (alkanes, alkenes, benzene) differs from that of alcohols and carboxylic acids.
- Boiling points of hydrocarbons (alkanes, alkenes, benzene) differ from those of alcohols.
- Density concepts are based on structures of alkanes and water.
Structures of Alkyl Substituents
- Sec-butyl, tert-butyl, isopropyl, and other alkyl substituents have specific structures.
Resonance
- Push arrows can be used to identify resonance in alkenes, carbonyl groups, carboxylic acids, amines, etc.
- Identifying most significant and least significant structures is important in resonance.
Acid-Base Reaction
- Identifying structures as acid or base is crucial.
- Increasing order of acidity can be determined using CARDIO and pKa.
- C-charge on atom, A-atom, R-resonance, DI-dipole induction, and O-orbitals (sp, sp2, sp3) are important concepts in acid-base reactions.
Spectroscopy
- Infrared spectroscopy (IR) involves identifying bands based on functional groups.
- Determining and calculating degree of unsaturation using HDI is important in IR spectroscopy.
