NaCl
Reason: NaCl is an ionic solid with strong ionic bonds that must be broken to boil, so it has a very high boiling point (~1413 °C). Comparisons: O2 is a small nonpolar molecule (bp ≈ −183 °C), H2O has strong hydrogen bonding (bp 100 °C), and C6H12O6 (glucose) is a covalent molecular solid that melts around ~146 °C and decomposes before it boils.
