When making 2-hexene, NaH is the only base that can cause the elimination process from 2-chlorohexane to make this product. Dan thinks that this reaction would be best run in Acenotrile,
The molar enthalpy of fusion of ice at 0 0C is 6.02 kJ/mol; the molar heat capacity of supercooled water is 75.3 J/molK. (a) One mole of supercooled water at -10 0C is induced to crystallize in a heat-insulated vessel.
Choose any two temperatures and corresponding vapor pressures in the table given, and use those values to calculate ?Hvap for dichloromethane (in kJ/mol).
