Question

Give the expected product of reaction of propyne with H2O in the presence of HgSO4 and H2SO4?

Answer 1

Explanation:

The major product obtained by the treatment of propyne with aqueous H2SO4 in the presence of HgSO4 is Acetone.

Hope it helps

Answer 2

Propyne reacts with water in presence of mercuric sulphate and sulfuric acid to form acetone.

The reaction step is as follows:

$\boxed{\sf{CH_{3}C\equiv CH \overset{H_{2}O,HgSO_{4}}{\underset{H_{2}SO_{4}}\longrightarrow} CH_{3}COH=CHCH_{3}}}$

Now , the product is extremely unstable in its en-ol form.

Hence , it undergoes tautomerization to form the keto structure of the compound.

$\boxed{\sf{CH_{3}COH=CHCH_{3}<=>CH_{3}COCH_{3}}}$

So, the final product of this reaction is acetone.
