Q. When propyne react with $H_{2}O$ in presence of dil. $H_{2}SO_{4}\ and\ HgSO_{4}$ product formed is
A) Acetone
B) Acetaldehyde
C) Acetic acid
D) Ethyl alcohol
Explanation
(a)
When propyne reacts with water in presence of $HgSO_{4}\ and\ H_{2}SO_{4}$ acetone is formed.
$CH_{3}C \equiv CH + H.OH\underset{H_{2}SO_{4}}{\overset{{Hg}^{2 +}}{\rightarrow}}CH_{3} - C = CH_{2}$
|
$\ \ \ OH$
$\overset{\rightarrow}{Ketonisation}CH_{3} - C - CH_{2}$
||
$O$
