In the boxes below, show the structural formulae of R, S and T obtained when Q is reduced to R and R undergoes dehydration to produce two different products S and T.
State the reagents that would be used for each reaction in a school or college laboratory: reduction; dehydration.
In the boxes below, write the structural formula of the organic compound formed when Q is reacted separately with each reagent under suitable conditions. If you think no reaction occurs, write NO REACTION in the box. The reagents are Tollens’ reagent, HCN, and $\text{K}_2\text{Cr}_2\text{O}_7/\text{H}^+$.
Apart from using a pH indicator, what reagent could you use to confirm the presence of some lactic acid in a sample of heptan-2-one? State the observation you would make.
