(a)
Interpretation:
Structure of Luminol and the various
Concept introduction:
Functional group: They are certain substitutes in the organic molecules which determine the characteristic reactions taking place in it.
Different types of functional groups are present and it includes
Primary and secondary amine:
Primary amine refers to the functional group that contains one nitrogen atom bonded to two hydrogen atoms and one carbon containing group and the secondary amine contains nitrogen bonded to one hydrogen atom and two carbon containing groups.
Carbonyl group: The functional group that contains carbon atom which is doubly bonded with the oxygen atom.
(b)
Interpretation:
Component of blood that catalyzes the fluorescence of Luminol has to be given.
Concept introduction:
Luminol:
- It is a solid which is soluble in polar organic solvents.
- It is important in
forensic studies since it can be used to determine trace amounts of blood at crime scenes. - Luminol on reaction with iron in the blood produces a blue glow.
(c)
Interpretation:
The purpose of the oxidizing agent in the Luminol solution has to be given.
Concept introduction:
Luminol:
- It is a solid which is soluble in polar organic solvents.
- It is important in forensic studies since it can be used to determine trace amounts of blood at crime scenes.
- Luminol on reaction with iron in the blood produces a blue glow.
