Question

What happens when
(i) acetylene is treated with hypochlorous acid;
(ii) acetylene is passed in a dilute solution of H2SO4
containing HgSO4;
(iii) Baeyer's reagent reacts with acetylene;
(iv) Propyne is passed through a red hot iron tube?

​

Answer 1

Answer:

In presence of Acid HgSO4 added a water molecule to the reactant compound. Here reactant compound is Acetylene. So, water will be added to acetylene. This addition is known as Markownikoff's addition.

C2H2 + H2O    -------(Hg+ and H+)----->  H3C=CH(OH).

again some water molecule will be added, therefore now C has two -OH which makes its unstable form [ CH3-CH(OH)2 ], which further results in the formation of ethanal ( CH3CHO ).
