Chemistry - Hydrocarbon Question with Solution | TestHub
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:
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)
Structure of A: A is a compound with D.B.E. . Since there's no (no water decolorization), it must have two rings.
Final Answer:
