Key Concepts:
- Iodoform Test
- Molecular formulas of organic compounds
- Reaction of organic compounds with HCl
Explanation:
The given organic compound A has the molecular formula CHO. The molecular formula CHO indicates that A is an aldehyde.
Iodoform Test:
The iodoform test is a chemical test used to identify compounds that contain the CH3CO group. When a compound with the CH3CO group is treated with iodine in the presence of a base, it undergoes a reaction that produces a yellow precipitate of iodoform.
Reaction of Compound A with Iodine:
When compound A undergoes the iodoform test, it indicates the presence of the CH3CO group. This means that compound A is an aldehyde with a methyl group attached to the carbonyl carbon.
Reaction of Compound A with HCl:
When compound A is saturated with HCl, it undergoes a reaction to form compound B with the molecular formula CHO. The molecular formula CHO indicates that B is also an aldehyde.
Identification of Compound B:
To identify compound B, we need to consider the reaction of compound A with HCl. The reaction of an aldehyde with HCl typically results in the formation of a hemiacetal or an acetal.
Correct Answer:
The correct answer is option C) Propanone and 2,6-dimethyl-2,5-heptadien-4-one.
