The Clausius-Clapeyron Equation (hopefully introduced to you in General Chemistry) can be used to relate the temperature and vapor pressure of a pure liquid given its heat of vaporization. It can be used to create a specialized nomograph for each compound as shown in Figure 6.1 of your text for hydrocarbons and carboxylic acids. In a simplified form it is given in Equation 6.1 of your book for nitrobenzene. ln(P1P2)=ΔHvapR(1T2−1T1) Given that: 0 °C = 273.15 °K, Hvap(benzaldehyde) = 45.9...
