Question

An organic compound 'A' has the molecular formula \( C_3H_6O \), it undergoes iodoform test. When saturated with dil. HCl it gives 'B' of molecular formula \( C_9H_{14}O \). A and B respectively are:

• A. Propanal and mesitylene
• B. Propanone and mesityl oxide
• C. Propanone and 2,6-dimethyl-2,5-heptadien-4-one
• D. Propanone and mesitylene oxide

Hint:

The iodoform test is a chemical reaction that identifies compounds containing a methyl ketone group or a structure that can generate it.

Answer 1

The Correct Option is B

The compound A reacts with iodoform reagent to give a yellow precipitate, confirming the presence of a methyl ketone group. Propanone undergoes this reaction to form mesityl oxide.
Final Answer: \[ \boxed{\text{Propanone and mesityl oxide}} \]
