Question

In the following reaction:
$C_{2}H_{2} \ce{ ->[{H_{2}O}][{HgSO_{4}/H_{2}SO_{4}}] }X \ce{<=>} CH_{3}CHO$
What is X?

• A. $CH_{3}CH_{2}OH$
• B. $CH_{3}-O-CH_{3}$
• C. $CH_{3}CH_{2}CHO$
• D. $CH_{2} = CHOH$

Answer 1

Answer: (D)

$\underset{\text{ACetylene}}{{HC \equiv CH}} \ce{ ->[{H_{2}O}][{HgSO_{4}/H_{2}SO_{4}}]}$
