(a)[3]
Deduce the value of $n$ in the formula and hence identify compound $G$.
(b)[2]
When magnesium reacts with $G$, a gas is produced. Name the gas and give a test and observation to identify this gas.
(c(i))[1]
Ethyl ethanoate has the same molecular formula as $G$. State the homologous series that ethyl ethanoate belongs to.
(c(ii))[1]
Give the structure for ethyl ethanoate.
(c(iii))[2]
Name the two compounds that, under suitable conditions, react to form ethyl ethanoate.
(c(iv))[2]
Compound $H$ is in the same homologous series as ethyl ethanoate, and $H$ has the same molecular formula as ethyl ethanoate. Suggest the name and the structure of $H$.
