An organic compound A has molecular formula and it is non-resolvable. A does not decolourize brown colour of bromine water solution. A on treatement with yields B as major product. B on treatment with yields which on treatment with yields three monochloro derivative. Also B on boiling with acidic permanganate solution yields . C on heating with sodalime yields . D on reducing with followed by heating the product with concentrated yields as major product. E on treatment with ozone followed by work-up with yields 6-Ketononanal.

Compound A is :

Options:

Answer:
A
Solution:

Question Explanation: Identify compound A by working backward from the final ozonolysis product.

Concept: Ozonolysis, Reduction, Dehydration, HBr Addition, and Reactions.

Solution: Final product, 6-Ketonoanal (a 9-carbon chain with a ketone at and an aldehyde at ).

Compound E ⟶ 6-Ketonoanal (Ozonolysis)

D → E (Dehydration/Elimination)

(Reduction)

(Hydrolysis/Acidic )

(Substitution/Rearrangement)
