The discussion centers on predicting bond enthalpy trends specifically for atom-hydrogen bonds, calculated using Gaussian software. It is established that for main group elements, bond dissociation energies (BDEs) decrease down the periodic table and increase across it. In contrast, for transition metals, M-H BDEs increase down the periodic table, although no clear trend is observed across the periodic table. A reference table from UCSB is provided for further insights into bond dissociation energies.
PREREQUISITESChemistry students, computational chemists, and researchers interested in bond enthalpy trends and their implications in chemical bonding and reactivity.
If you calculated the bond enthalpies, wouldn't you be in a better position to tell us the trend, rather than us telling you?ReidMerrill said:Need to find a trend in predicting the bond enthalpy of several atom-hydrogen bonds I calculated using gaussian.
I just wondered if there was supposed to be a trend since they don't appear to follow any pattern.TeethWhitener said:If you calculated the bond enthalpies, wouldn't you be in a better position to tell us the trend, rather than us telling you?
