Chapter 1General Organic Chemistry — Foundations
- Welcome to Organic Chemistry: The Map
If organic chemistry has ever felt like everyone got a manual you didn't — start here. The map for the whole subject, and why carbon earns its own branch.
- Why Carbon Runs the Show
Why does one element out of 118 get a whole branch of chemistry? Carbon's electrons, its four bonds, and its talent for bonding to itself — explained from the ground up.
- Octet, Its Exceptions & Counting Electrons Right
The octet rule breaks more often than you think. The three ways it fails — electron-deficient, expanded, and odd-electron — and how to spot each on sight.
- What is a Bond?
What a covalent bond really is: two orbitals overlapping. Sigma vs pi bonds, why a double bond isn't twice a single, and how to count the σ and π bonds in any molecule.
- Hybridization: The sp / sp² / sp³ Toolkit
How orbital mixing gives carbon its sp, sp² and sp³ shapes — and how to spot which one any carbon is, on sight, straight from its bonds.
- Dipole Moment & Physical Properties
The chapter's payoff: add bond dipoles like vectors to predict polarity (why CO2 is nonpolar but water isn't), and connect it all to boiling point, solubility, and hydrogen bonding.
- Degree of Carbon and Hydrogen Atoms
Label every carbon 1°, 2°, 3° or 4° by the company it keeps — and its hydrogens with it. The one classification that drives carbocation stability, radical reactions and product-counting.
- Relative Acidity of Hydrogen Atoms
Why one hydrogen lets go of its proton and another never does — ranked by the stability of the anion left behind: hybridization, resonance, induction and aromaticity.
