🔬 The Carboxylic Acid Family Structure
General Formula: CₙH₂ₙ₊₁COOH (or CₙH₂ₙO₂)
- All carboxylic acids contain the -COOH functional group
- The carboxyl group is always at the end of the carbon chain
- Example: Ethanoic acid = CH₃COOH = acetic acid (vinegar)
The First Four Carboxylic Acids (Essential to memorise!):
Figure 1: The -COOH group contains both a C=O (carbonyl) and an -OH combined. The H in -COOH is the acidic hydrogen that can be donated as H⁺ in solution.
