From the experimental results in the table above, work out which group(s), as well as the benzene ring, are present in each of the four isomers $J$, $K$, $L$ and $M$. Fill in the table below by identifying the group(s) in each isomer.
What reaction type occurs in test 5 when $M$ is changed into $P + Q$?
Suggest possible structures for compounds $P$ and $Q$. $P$ ($\text{C}_6\text{H}_7\text{N}$) $Q$ ($\text{C}_3\text{H}_5\text{O}_2\text{Na}$)
Isomers $J$, $K$, $L$ and $M$ all share molecular formula $\text{C}_9\text{H}_{11}\text{NO}$. Using the information in (a), suggest a structure for each isomer and draw them in the boxes. Circle every chiral centre in $K$ and $L$.
Compound $N$ is another isomer with the same molecular formula $\text{C}_9\text{H}_{11}\text{NO}$ and it also contains a benzene ring. $N$ has the same functional group as $M$. When $N$ is heated with $\text{NaOH(aq)}$, ethylamine and a sodium salt $W$ are formed. Suggest the structure of $W$.
