Provide answers to the following
(c) Name and give the formula of a reagent that you could use to convert benzyl alcohol, CoHsCH2OH into benzaldehyde, CHsCHO. In the carbonyl group, oxygen is more electronegative than carbon and the oxygen atom bears two lone pairs of electrons whereas carbon has none. How do these features affect the reactivity of the functional group? 15 marksl (d) The reaction of an aldehyde with an amine to give an imine is catalysed by a trace of acid. Write the complete mechanism for this reaction. Although imine formation is acid catalysed it is inhibited by high concentrations of acid. Suggest an explanation for this behaviour NCH3 CH3-NH2 + H20 15 marks]
