The given compound is CH3CH2CH2-CH C2H5 CH3 2. To identify the major product s formed in a rearrangement reaction, we need to consider the most stable carbocation intermediate that can be formed. In this case, a hydride shift can occur, leading to the formation of a more stable tertiary carbocation.The rearrangement reaction proceeds as follows:1. A hydride H- shift occurs from the CH3CH2CH2 group to the adjacent carbon, forming a tertiary carbocation: CH3CH2C+ CH3 -CH C2H5 CH3 2.2. The carbocation can now lose a proton H+ to form an alkene, resulting in the major product.The major product formed in this rearrangement reaction is:CH3CH2CH=CH C2H5 CH3 2
