Question 28

An alcohol, A\text{A}A, has the molecular formula C4H9OH\text{C}_4\text{H}_9\text{OH}C4​H9​OH.

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}_2C4​H8​O2​.

a.

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.
