Summary

This section introduces alkanes, emphasizing their importance as saturated hydrocarbons without reactive functional groups, and it lays the groundwork for systematic organic nomenclature. It covers the concepts of structural isomerism, alkyl groups, and the key aspects of naming compounds using IUPAC rules. In addition, the chapter highlights the three-dimensional aspects of molecular structures by analyzing conformations via Newman projections. Understanding these principles is critical for predicting both the physical and chemical properties of organic compounds, as well as for practical applications in areas such as fuel refinement.

CONCEPT

DEFINITION

Acid–Base Chemistry

The study of acids and bases using both the Brønsted–Lowry (proton-donating/accepting) and Lewis (electron pair accepting/donating) frameworks, including quantification via pKa values, which together explain chemical reactivity in organic molecules. •

Example Problems

Example 1

Identify the functional groups in each of the following molecules: (a) Methionine, an amino acid: (b) Ibuprofen, a pain reliever: (c) Capsaicin, the pungent substance in chili peppers:

Example 2

Propose structures for simple molecules that contain the following functional groups: (a) Alcohol (b) Aromatic ring (c) Carboxylic acid (d) Amine (e) Both ketone and amine (f) Two double bonds

Example 3

Identify the functional groups in the following model of arecoline, a veterinary drug used to control worms in animals. Convert the drawing into a linebond structure and a molecular formula (red $=\mathrm{O},$ blue $=\mathrm{N}$ ).

Example 4
