4. In terms of intermolecular interactions, try to account forthe differences in melting point between salicylic acid (mp158.6°C) and acetanilide (mp 114.3°C).
5. Isobutyric acid has a solubility in water (at 25°C) aboutoneâ€third of its solubility in diethyl ether; thus Kd = 3.0.Imagine 4.0 g of isobutyric acid dissolved in a mixture of 35.0 mlof diethyl ether and 100.0 ml of water. a) What weight of acid isin each layer at equilibrium after an extraction?
6. What will be the appearance of a TLC plate if a solvent oftoo low of a polarity is used for its development? Too high of apolarity?
