![]() ![]() The case of dichlorocarbene, with a difference in AH of 15 kcal/mol), is particularly disturbing and has been analysed in some detail.134 Notably, the PA of CCl2 from an earlier bracketing experiment126 was closer to the enthalpy-derived PA. The proton affinities obtained by ICR bracketing125 (Table 6) are consistently lower than those derived from enthalpies of formation (Table 7). 8 and 9 have both been applied to halocarbenes. Thermonator 3.These gases have lower thermal stabilities than hydrogen sulphide as expected from their enthalpies of formation Table 10.2) and they are consequently more powerful reducing agents than hydrogen sulphide.
