What is meant by the term ‘hydrocarbon’?
A hydrocarbon is a compound made up of only hydrogen and carbon atoms.
What are the two main products of cracking?
Short-chain alkanes and alkenes.
Why is cracking useful in the petrochemical industry?
Cracking produces smaller, more useful hydrocarbons such as petrol and alkenes, which are used in making polymers.
What is the difference between an alkane and an alkene?
Alkanes are saturated hydrocarbons with only single bonds, whereas alkenes are unsaturated hydrocarbons with at least one double bond.
Write the word equation for the complete combustion of ethanol.
Ethanol + Oxygen → Carbon dioxide + Water
What two functional groups are present in a carboxylic acid?
A hydroxyl (–OH) group and a carboxyl (–COOH) group.
Why are alcohols used as fuels?
Alcohols, such as ethanol, burn cleanly and release a significant amount of energy.
Name a natural polymer and the monomer it is made from.
Natural polymer: Proteins
Monomer: Amino acids
What is the main use of alkenes in industry?
Alkenes are used to make polymers and plastics.
How does condensation polymerisation differ from addition polymerisation?
In condensation polymerisation, monomers join together and a small molecule (such as water) is released, whereas in addition polymerisation, monomers join without producing a by-product.
