Carboxylic Acids & Derivatives — three ways to learn it.

The complete written lesson — the –COOH group & nomenclature, preparation routes, why carboxylic acids are acidic (the resonance-stabilised carboxylate ion), salt formation & esterification, and the derivatives: esters, acyl chlorides & amides with their relative reactivity.

As you scroll, a live D3 panel animates every idea: the two equivalent resonance forms of the carboxylate ion, –COOH releasing H⁺ into water, the esterification hero scene where an acid and an alcohol lose water to make a fruity-smelling ester, the reactivity ladder of derivatives, and soap forming by saponification.

Warm a carboxylic acid + alcohol with a drop of conc. H₂SO₄ and watch the sweet-smelling ester form — a reversible reaction whose yield levels off at equilibrium.
