14) Based on Table A (above) showing measured heats of formation, which of the following has the strongest bonds?

1 point
SnO (s)
ZnO (s)
NaCl (s)
NaF (s)
To determine which compound has the strongest bonds, we need to compare the values of the measured heats of formation from Table A.
Looking at the options, SnO (s), ZnO (s), NaCl (s), and NaF (s), we can compare their respective heats of formation:
- SnO (s): -212 kJ/mol
- ZnO (s): -348 kJ/mol
- NaCl (s): -411 kJ/mol
- NaF (s): -570 kJ/mol
The more negative the value of the heat of formation, the stronger the bond. Therefore, based on these values, NaF (s) has the strongest bonds, as it has the most negative heat of formation.
