An alcohol, A\text{A}A, has the molecular formula C4H9OH\text{C}_4\text{H}_9\text{OH}C4H9OH.
Alcohol A\text{A}A can be oxidised to a compound, B\text{B}B, with the molecular formula C4H8O2\text{C}_4\text{H}_8\text{O}_2C4H8O2.
Compound B\text{B}B is not an alcohol but is a member of another homologous series.
Write down the name of this homologous series.
Draw the displayed formula of a molecule of alcohol A\text{A}A and of a molecule of compound B\text{B}B (assuming both are straight-chain molecules with the functional group on the terminal carbon). Show all the covalent bonds.
