This question is about organic compounds. Which two statements about members of a homologous series are correct? Tick two boxes. They have similar chemical properties. They have similar physical properties. They have the same functional group. They have the same relative molecular mass. They have the same number of carbon atoms.  To which homologous series do methane and ethane belong? Methane and ethane are both hydrocarbons. What is meant by the term hydrocarbon? Draw the structure of ethane showing all of the atoms and all of the bonds.  The hydrocarbon tetradecane, C14H30, can be cracked to form a mixture of alkanes and alkenes. State two conditions needed for cracking.  Complete the chemical equation for the cracking of tetradecane to form two different hydrocarbons. C14H30 C3H6 +  Ethanol can be manufactured from ethene. Complete the word equation for this reaction. ethene + ethanol Ethene can be polymerised to form poly. Complete the sentence about this reaction using words from the list. addition condensation ions monomers oxidation polymers Ethene combine to form polyby polymerisation.
