उत्तर
2-Methylpropan-2-ol undergoes dehydration when passed over hot copper at 573 K.
\[\begin{array}{cc}
\ce{H3C - C(OH) - CH3 ->[Cu/573K][dehydration] H3C - C = CH2}\\
\phantom{}|\phantom{...............................}|\phantom{.}\\
\phantom{....}\ce{\underset{\text{2-Methylpropan-2-ol}}{CH3}\phantom{..................}\underset{\text{2-Methylpropene}}{CH3}}\phantom{....}
\end{array}\]
