How many methane, ethylene and acetylene be prepared in the laboratory? Write the chemical reactions involv?

Question

What type of reaction is exhibited by alkenes? Why?

these question are from the experiment entitled "Hydrocarbons – Structure and Chemical Properties"
the substances used are: benzene, n-hexane, cyclohexane, kerosene and gasoline.
the test are: ignition test, baeyer's test, reaction with sulfuric acid and Br2 in CCl4

Answer 1

Methane is prepared by reacting sodium ethanoate with sodium hydroxide. It's called decarboxylation.

Ethene is prepared by the dehydration of ethanol using concentrated sulphuric acid at 180 degrees C.

Ethyne is made by reacting calcium carbide with water.
