| Abstract: | An empirical method for estimating the standard enthalpy of some polar compounds is presended in this paper, that is △△fH°(RX/CH3X)= △fH°(RX)- △fH°(CH3X)=a+bIx where △△fH°(RX/CH3X) represents the standard enthalpy difference between CH3-X and R-X(R=Et, i-Pr, t-Bu, etc). It is a new polarity parameter defined by us. A good result was obtained for nearly 70 polar compounds. |
| Keywords: | Standard enthalpy Polarity parameter Correlate Estimate Polar organic compound |
