For 2-ethylpentanoic acid [CCCC \((\mathrm{CC}) \mathrm{C}(=\) O)O; 020225-24-5], hardly any data are available in the database. To evaluate this molecule, \(T_{\mathrm{b}}, T_{\mathrm{m}}, \Delta H_{\text {fus }}\), and vapor pressure as a function of temperature are needed. Is this compound soluble in water? Which property models should be used to generate the missing data?
