Questions & Step-by-Step Solutions
What is the product of the complete combustion of an alkyne?
Correct Answer: Carbon dioxide (CO2) and water (H2O)
Step 1: Understand what an alkyne is. Alkynes are hydrocarbons that contain at least one triple bond between carbon atoms.
Step 2: Know what combustion means. Combustion is a chemical reaction that occurs when a substance reacts with oxygen, usually producing heat and light.
Step 3: Identify the products of complete combustion. In complete combustion, the carbon in the alkyne reacts with oxygen to produce carbon dioxide (CO2) and water (H2O).
Step 4: Write the general equation for the complete combustion of an alkyne. The general formula is: CnH2n-2 + O2 → CO2 + H2O.
Step 5: Conclude that the complete combustion of any alkyne will always produce carbon dioxide and water.
