💡 Solution & Explanation

Correct answer: \(\text{A}\). Elimination removes \(\ce{HX}\) from adjacent carbons. Product preference follows substrate structure, anti-periplanar geometry, and Zaitsev/Hofmann control where applicable. Recovered question text: 28. An unknown alkyl halide (A) reacts with alcoholic KOH to produce a hydrocarbon (C4H8). Ozonolysis of the hydrocarbon affords one mole of propionaldehyde and one mole of formaldehyde. Suggest which organic structure among the following is the correct structure of the above alkyl halide (A)? (a) CH3(CH2)3Br (b) CH3CH(Br)CH(Br)CH3 (c) CH3CH2CH(Br)CH3 (d) Br
