(a)
Interpretation:
A curved-arrow mechanism that involves the important intermediates for the formation of pyridoxamine phosphate is to be stated. The significance of the pyridinium ion in the catalysis of the given reaction sequence is to be stated.
Concept introduction:
The curved-arrow notation is used to show the transfer of electrons from one atom to another. The curved arrow has two barbs (head and tail) which represent the direction of electron flow.

- (a) Explain the mechanism of a nucleophilic attack on the carbonyl group of an aldehyde or a ketone.(b) An organic compound (A) (molecular formula CgH16Q2) was hydrolysed with dilute sulphuric acid to give a carboxylic acid (B) and an alcohol (C). Oxidation of (C) with chromic acid also produced (B). On dehydration (C) gives but-1-ene. Write the equations for the reactions involved.arrow_forwardThe saccharide shown here is present in some plant-derived foods. (a) Indicate the anomeric carbon atom(s) in this structure by drawing a circle around the atom(s) or by drawing an arrow pointing to the atom(s). (b) Would this saccharide give a positive result with Benedict’s reagent? Why or why not? (c) Would this saccharide give a positive result with Barfoed’s reagent? Why or why not? (d) Would this saccharide give a positive result with Seliwanoff’s reagent? Why or why not? (e) In a separate set of experiments, the saccharide solution was treated with a reagent that breaks glycosidic bonds. After this treatment, would any of the three assays give different results?
