Assertion : Reaction of but-1-ene with HBr gives 1-bromobutane as major product. Reason : Addition of hydrogen halides to alkenes proceeds according to Mar
Explain why heats of hydrogenation cannot be used to determine the relative stability of 2-methylpent-2-ene and 3-methylpent-1-ene. How is the heat of combustion related to hyperconjugation? Why doesn't benzaldehyde undergo a self-aldol condensation? Why is condensation ex...
Correct statement. Addition of water to but-1-ene in acidic medium yields butan-2-ol. Correct reason. Adddition of water in acidic medium proceeds through the formation of secondary carbocation.

Assertion is correct but reason is incorrect because 1-butene on reaction with HBr in the presence of a peroxide produces 1-bromobutene. In this reaction, secondary free radical is formed as intermediate product. (i)(a)(C6H5CO)2 O2 to 2C6H5COO^(.) (b
