Resumen del Recurso

Pregunta Respuesta
Carboxylic Acid General Formula CnH2nO2
Benzoic Acid Acid group attached to benzene ring
Physical properties # High BP for relative mass
As length of Carbon chain increases BPT increases - the bigger the molecule the more VDW
Boiling Point increases with straight molecules # Greater branching # Lower intermolecular VDW forces # Low BPT
Solubility # H bonds form between H2O molecules and individual molecules of acid
Solubility decreases with size # Longer hydrocarbon tails get between water molecules and break H bonds
