(a)
Interpretation:
The amino acids required for obtaining the given aldehyde and the compound responsible for purple coloration need to be identified.
Concept introduction:
Ninhydrin react with primary
To draw : To identify the amino acids required to form the given
(b)
Interpretation:
The amino acids required for obtaining the given aldehyde and the compound responsible for purple coloration need to be identified.
Concept introduction:
Ninhydrin react with primary amines to give a purple colored product. This is a qualitative and quantitative test. The aldehyde is obtained as by-product. The general scheme can be shown as,
To draw : To identify the structure of compound responsible for purple color.
(c)
Interpretation:
The amino acids required for obtaining the given aldehyde and the compound responsible for purple coloration need to be identified.
Concept introduction:
Ninhydrin react with primary amines to give a purple colored product. This is a qualitative and quantitative test. The aldehyde is obtained as by-product. The purple coloration is seen due to compound that has more conjugated systems. The more conjugation is present in the system the more colored the compound will be. The general scheme can be shown as,
To draw : To identify the origin of the purple color.

- Identify the missing organic reactants in the following reaction: X + Y H+ two steps Note: This chemical equation only focuses on the important organic molecules in the reaction. Additional inorganic or small-molecule reactants or products (like H2O) are not shown. In the drawing area below, draw the skeletal ("line") structures of the missing organic reactants X and Y. You may draw the structures in any arrangement that you like, so long as they aren't touching. Click and drag to start drawing a structure.
