AIIMS 2019 Chemistry Carbocation Stability MCQ Question

When HBr attacks the left side double bond of the conjugated diene, it leads to the formation of a tertiary carbocation, which is stabilized by hyperconjugation and inductive effects from adjacent alkyl groups. Conversely, if HBr attacks the right side double bond, a secondary carbocation is formed, which is less stable due to fewer alkyl groups providing stabilization. This difference in carbocation stability is crucial in determining the major product of the reaction, favoring the pathway that leads to the more stable tertiary carbocation. Other options may suggest incorrect pathways or misinterpret the stability of the carbocations formed.
