Q. In the following reaction, $C_{2} H_{2} H_{2} O H g S O_{4} / H_{2} S O_{4} X ⇌ C H_{3} C H O$ , What is $X$ ?

$C H_{3} C H_{2} O H$

$C H_{3} - O - C H_{3}$

$C H_{3} C H_{2} C H O$

$C H_{2} = C H O H$

$H C \equiv C H H_{2} O H g S O_{4} / H_{2} S O_{4} 6 0^{\circ} C$
$[C H_{2} = X C H O H] Tautomerisation C H_{3} C ∣∣ O H O$
