Tertiary alcohols undergo dehydration to form alkenes on reaction when their vapours are passed over heated copper at 300°C <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/dfd57faf9dc5a666fd42c601b7a4fce4-.jpeg" />

Q. What product forms when $(C H_{3})_{2} C (O H) C H_{2} C H_{3}$ is treated with $C u$ at $30 0^{\circ} C$ ?

$(C H_{3})_{2} C (= O) C H_{2} C H_{3}$

$(C H_{3})_{2} C (= O) C (= O) C H_{3}$

$(C H_{3})_{2} C H_{2} C H_{2} C H_{3}$

$(C H_{3})_{2} C = C H C H_{3}$

Tertiary alcohols undergo dehydration to form alkenes on reaction when their vapours are passed over heated copper at $30 0^{\circ} C$
