Question

How will you convert propyne to acetone?

Answer 1

Hint: When the propyne is made to undergo the reaction with the reagents like mercuric sulphate and then followed by its hydrolysis, then the end product of this reaction is the acetone and thus, the propyne is converted. Now, you can easily write the reaction involved in it.

Complete step by step solution:
Propyne is a member belonging to the family of the alkynes which are those hydrocarbons which consist of the triple bond between the carbon atoms and are, thus, also called as the unsaturated hydrocarbon and their general chemical formula is ${{C}_{n}}{{H}_{2n-2}}$ Propyne has three carbon as the name indicates (prop=3 and yne= triple bond) and thus, has the molecular as ${{C}_{3}}{{H}_{5}}$.
On the other hand, acetone is member belonging to the family of the ketone which consists of -C=O group in their compounds and like the propyne, it also consists of the three carbon atoms in it and has the molecular formula as ${{C}_{3}}{{H}_{4}}O$.
Propyne can be converted to the acetone when it is made to undergo the reaction with mercuric sulphate followed by hydrolysis and thus, resultant product, thus formed is acetone. The reaction occurs as:

Acetone is a colourless liquid with a pleasant and fruity odour.
Thus, in this way, we can convert propyne into the acetone.

Note: acetone is used in the makeup products i.e. the cosmetics, in foods, can be used to denature certain alcohols, and is a very important laboratory reagent and is used in the production of the many other chemical compounds.
