Define the term homologous series.
Give two reasons to account for the general unreactivity of alkanes.
Alkanes with low relative molecular mass, $M_r$, are more useful than those in heavier crude oil fractions. Name the process used to obtain alkanes with low $M_r$ from heavier crude oil fractions.
Hexane, $\mathrm{C_6H_{14}}$, has four structural isomers. Fig. 3.1 shows hexane and two of its structural isomers. Complete Fig. 3.1 by drawing the structures of C and D, the other two structural isomers of hexane.
A, B and hexane have different boiling points. Put A, B and hexane in order of increasing boiling point. Explain your answer.
Hexane can be converted into compounds E and F at high temperature and pressure. Fig. 3.2 shows the reaction scheme involving hexane, E and F. Identify a suitable reagent for reaction 3.
Use the data in Fig. 3.2 and in Table 3.1 to calculate the enthalpy change of reaction 2, $\Delta H_2$.
Write an equation for the complete combustion of hexane.
