Suggest which functional group is causing the reaction with sodium.
Suggest which functional group is responsible for the reaction with Fehling's solution.
The bromine test result indicates that a functional group is missing from compound $J$. Suggest what this functional group is.
In the boxes below, draw three straight-chain structures for $J$ that satisfy the results above and are structural isomers of one another.
Compound $J$ reacts with alkaline aqueous iodine to produce a pale yellow precipitate. Which functional group does this reaction show that $J$ has?
Which one of your three structures $K$, $L$ or $M$ contains this group and is therefore $J$?
Compound $J$ exists as stereoisomers. Name the kind of stereoisomerism shown by $J$.
Draw two structures of $J$ that demonstrate this stereoisomerism.
