These groups are ordered in the wrong way. In addition the groups were found in Table 38 (ordered in the correct way) but with different values. Selected values are taken from table 38. C_(C)(C*)(C) -1.90 C_(C)(C*)(C)(C) 1.50 Some additional group estimations : ---------------------------------- O_(CO*)(O) estimated as -3.40 from O_(CO)(O) and using the differences found between O_(CO) and O_(CO*) and O_(CO)(C) and O_(CO*)(C). Of course, highly uncertain O_(CO)(ONO2) = O_(CO)(O) + O_(NO2)(O) = -15.00 and setting group for ONO2_(O) to 0. O_(CO*)(ONO2) = O_(CO*)(O) + O_(NO2)(O) = 0.60 CO_(CO*) and CO*_(CO) : I did not find any useful data to estimate those groups. I used the minimum of bond dissociation energy linked to H-COR (i.e. 360 kJ) that I found in the Handbook (see ref). Then using -211.9 kJ for the formation heat of glyoxal gives -69.9 kJ for the heat of formation of HCO-CO. Finally, setting CO*_(CO) to 0 gives a group contribution of -16.9 kcal for CO_(CO*). CO_(CO*)(C) : same approach as for CO_(CO*) above. Using methyl glyoxal (instead of glyoxal) leads to CO_(CO*)(C)=-20.65 kcal CO_(CO*)(O) : use value given for above for CO_(CO*)(C), increased by 0.1 which corresponds to the difference between CO_(CO)(C) and CO_(CO)(O) C_(C)(CO)(CO)(ONO2) = C_(C)(CO)(CO)(O) + O_(C)(NO2) = -27.97 C*_(C)(CO)(ONO2) = C*_(C)(CO)(O) + O_(C*)(NO2) = 20.01 C_(C)(CO)(CO)(O*) = C_(C)(CO)(CO)(O) +14.19=5.62 14.19 is the difference between C_(C)(O*) and C_(C)(O) C_(C)(CO)(O*)and C_(C)(CO)(O) C_(CO)(O*) and C_(CO)(O) C_(CO)(CO)(CO)(O) : estimated to be around -5.50, based on the following data available for C_{(C)or(CO)}(O) : C_(C)(O) : -8.10 C_(C)(C)(O) : -7.20 C_(CO)(O) : -6.95 C_(C)(C)(C)(O) : -6.60 C_(C)(CO)(O) : -6.32 C_(C)(C)(CO)(O) : -5.70 Note that the data given for C_(C)(CO)(CO)(O) : -8.57 seems too high C*_(CO)(CO)(O) : set equal to C*_(C)(CO)(O) (32.46) decreased by 1.5 due to the substitution of (C) to (CO) => 30.96 C_(CO)(CO)(CO) estimated to be -5.00 based on : C_(C)(C) : -4.93 ; C_(C)(CO) : -5.20 ; C_(CO)(CO) : -7.60 C_(C)(C)(C) : -1.90 ; C_(C)(C)(CO) : -1.70 ; C_(C)(CO)(CO) : -4.57 C*_(CO)(CO) : set equal to C*_(C)(CO) (38.58) decreased by 1.5 due to the substitution of (C) to (CO) => 37.1 C_(CO)(CO)(CO)(O*) = C_(CO)(CO)(CO)(O) + 14.19 (see above) C_(CO*)(C)(O) = C_(CO)(C)(O) -5.00 = -1.30 ; based on the decrease between C_(CO*) and C_(CO) C_(CO*)(O) and C_(CO*)(C) CO_(CO*)(CO) = CO_(CO)(CO) + 8.4 = -18.5 based on the differences between CO_(CO) and CO_(CO*) CO_(CO)(C) and CO_(CO*)(C) C_(CO*)(CO)(O) = C_(CO)(CO)(O) +8.4= -0.80 /// C_(Cd)(CO)(O*) = 6.98 based on C_(C)(CO)(O*) - difference between C_(C)(O*) and C_(Cd)(O*) coherent with the value for C_(CO)(O*) : 7.24 CO_(Cd)(CO) estimated to be -29.20 based on : no difference between CO_(C) and CO_(Cd) so there is difference between CO_(Cd)(CO) and CO_(C)(CO) C_(Cd)(C)(O*) = 6.95 based on C_(C)(C)(O*) - difference between C_(C)(O*) and C_(Cd)(O*) C_(Cd)(CO)(O) = -4.92 based on C_(C)(CO)(O) - difference between C_(C)(CO) and C_(Cd)(CO) C_(Cd)(C*) = -4.78 based on C_(C)(C*) + difference between C(Cd)(C) and C(C)(C) Cd_(C*)(Cd) 4.85 C*_(Cd) 35.84 are calculated to imply a k decomposition for Cd=Cd-CH2-CH2O. equal to (k reaction with O2 * [o2]) Actually, Cd_(C*)(Cd) + C*_(Cd) = 37.65 , so the two thermochemical groups are adjusted with the mean values of the Cd_ groups and the C*_ groups.
