Vedclass · Answer

(B) The reaction involves the acid-catalyzed dehydration of $3,3-dimethylbutan-2-ol$. $1$. Protonation of the $-OH$ group leads to the formation of a secondary carbocation: $(CH_3)_3C-CH^+(CH_3)$. $2$. This secondary carbocation undergoes a $1,2-methyl$ shift to form a more stable tertiary carbocation: $(CH_3)_2C^+-CH(CH_3)_2$. $3$. Loss of a proton from the adjacent carbon atom results in the formation of the most stable alkene,which is $2,3-dimethylbut-2-ene$ $(CH_3-C(CH_3)=C(CH_3)_2)$. Thus,the major product is $2,3-dimethylbut-2-ene$.

The major product formed in the following reaction is :
