(a)[2]
State two features of a homologous series.
(b)[2]
Draw the structures of the branched and straight-chain alkanes with four carbon atoms. Include every atom and every bond.
(c(i))[2]
Describe the way the melting points of these alkanes vary as the number of carbon atoms changes.
(c(ii))[1]
Use the graph to estimate the melting point of the unbranched alkane with ten carbon atoms.
(d(i))[2]
Construct the equation for the complete combustion of pentane, C$_5$H$_{12}$.
(d(ii))[2]
Name the products of the incomplete combustion of pentane and explain why the incomplete combustion of hydrocarbons is dangerous to health.
