For which change would van der Waals’ forces be the only intermolecular forces that must be overcome?
- Aevaporation of ethanol, $\text{C}_2\text{H}_5\text{OH(l)} \rightarrow \text{C}_2\text{H}_5\text{OH(g)}$
- Bmelting of ice, $\text{H}_2\text{O(s)} \rightarrow \text{H}_2\text{O(l)}$
- Cmelting of solid carbon dioxide, $\text{CO}_2\text{(s)} \rightarrow \text{CO}_2\text{(l)}$
- Dsolidification of butane, $\text{C}_4\text{H}_{10}\text{(l)} \rightarrow \text{C}_4\text{H}_{10}\text{(s)}$
