Vedclass · Answer

(C) The reaction involves the acid-catalyzed dehydration of $3,3$-dimethylpentan-$2$-ol using concentrated $H_2SO_4$ at high temperature. $1$. Protonation of the $-OH$ group occurs to form a good leaving group $(-OH_2^+)$. $2$. Loss of water generates a secondary carbocation at the $C-2$ position. $3$. This secondary carbocation undergoes a $1,2$-methyl shift to form a more stable tertiary carbocation at the $C-3$ position. $4$. Elimination of a proton from the adjacent $C-4$ position (following Zaitsev's rule) yields the most stable,highly substituted alkene,which is $3,4$-dimethylpent-$2$-ene.
