How do I solve this Alkyne synthesis homework problem for my Organic Chemistry II class? I have to provide both the intermediate products and the reagents used.
Substance X is known to exist at 1 atm in the solid, liquid, or vapor phase, depending on the temperature. Additionally, the values of these other properties of X
have been determined:
melting point
enthalpy of fusion
90. °C
8.00 kJ/mol
boiling point
130. °C
enthalpy of
vaporization
44.00 kJ/mol
density
2.80 g/cm³ (solid)
36. J.K mol (solid)
2.50 g/mL (liquid)
heat capacity
32. J.Kmol (liquid)
48. J.Kmol (vapor)
You may also assume X behaves as an ideal gas in the vapor phase.
Ex
Suppose a small sample of X at 50 °C is put into an evacuated flask and heated at a constant rate until 15.0 kJ/mol of heat has been added to the sample.
Graph the temperature of the sample that would be observed during this experiment.
