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. o0o 150- 140 130- 120- 110- 100- G Ar ?

Mechanism. Provide the mechanism for the reaction below. You must include all arrows, intermediates, and formal charges. If drawing a Sigma complex, draw all major resonance forms. The ChemDraw template of this document is available on Carmen. Br FeBr3 Br
