Ninhydrin reacts with an amino acid to form a product that has the colour:
Correct answer: C. Bluish violet
- A. Blue
- B. Violet
- C. Bluish violet
- D. Red
Explanation
Ninhydrin reacts with the α-amino group of primary amino acids producing 'Ruhemann's purple'. To detect the presence of amino acids , they're made to react with the ninhydrin reagent which is basically yellow in color, but when reacted with the amino acids, the resultant product is in purple colour which indicates that amino acid is present in that very compound.Bluish violet is correct, ref ptb part 2 chem pg 262 (Ninhydrin Test).

About Alkyl Halides
Alkyl halides are named and related to their carbon-halogen structure, polarity and reactivity. The key reactions are nucleophilic substitution by SN1 and SN2 mechanisms and elimination by E1 and E2 mechanisms, including how substrate structure, nucleophile, base, solvent and temperature influence substitution versus elimination.
