Question

AANE LYSULAW Which of the other hydrocarbons that you studied in this experiment has an odor to p-dichlorobenzene? 4. Synthesis of Acetylene Describe what happened when water was added to calcium carbide. What did you observe when the burning splint was thrust into the test tube? Is acetylene unsaturated? What is your evidence? Write an equation for the synthesis of acetylene. Write an equation for the combustion of acetylene. Did the purple color of potassium permanganate disappear? What color product was formed? Does this confirm that acetylene is unsaturated? Write an equation for the reaction that occurred.

Answer 1

100 - C₂H2 + Cacou ( Not balanced) Cacz + H₂O (calcium carbide) Acetylene is formed - - Acetylene starts burning, gives co2f H2Oo, heat Yes, it is unsaturated (HCECH I as on burning sti, smag that indicates it contains ligh % carbon content of high cuneatulation Dovedul black - C2H₂ + 3 O2 + 2CO2 + H2O (Gmbution Reaction) - CaCat H2o - CzHz ( synthesis).
