Vedclass · Answer

(D) The reaction is the acid-catalyzed dehydration of an alcohol using $H_3PO_4$ and heat.$1.$ It is a dehydration reaction as a water molecule is removed.$2.$ The mechanism is $E_1$,not $E_2$,as it involves the formation of a carbocation intermediate.$3.$ The reaction involves a $1,2-methyl$ shift (carbon skeleton migration) to form a more stable carbocation.$4.$ The major product is the most stable alkene (the one with more $\alpha-hydrogens$,i.e.,$12 \alpha-H$ in this case).$5.$ It is a multi-step reaction involving carbocation formation and rearrangement.Therefore,statements $1, 3,$ and $4$ are correct.
