The equation for one reaction that occurs when a long-chain alkane is cracked is:
CxHy→C8H18+2C4H8 \text{C}_{x}\text{H}_{y} \rightarrow \text{C}_8\text{H}_{18} + 2\text{C}_4\text{H}_8 CxHy→C8H18+2C4H8Deduce the molecular formula of CxHy\text{C}_{x}\text{H}_{y}CxHy.
Give the IUPAC name for C8H18\text{C}_8\text{H}_{18}C8H18.
Draw the displayed formula of but-1-ene, C4H8\text{C}_4\text{H}_8C4H8.
But-1-ene can undergo addition polymerisation to form poly(but-1-ene). Draw the displayed formula for the repeat unit of poly(but-1-ene).
