Get C2H2 from C2H4Br2.

| April 21, 2021 | education

We need to get another organic compound, acetylene, from an organic compound, the halogenated hydrocarbon 1,2-dibromoethane. For this, it is necessary to carry out the reaction of interaction of 1,2 – dibromoethane with potassium hydroxide in liquid form. As a result of such a chemical reaction, we get the acetylene we need, also in this reaction water and potassium bromide salt are formed. Graphically, this equation of a chemical reaction can be expressed as follows:

C2H4Br2 + 2 KOH = C2H2 + 2 KBr + 2 H2O

In order to equalize this equation of the chemical reaction, we need to put the number 2 in front of the potassium hydroxide, in the reaction products, before the salt with potassium bromide, we put the number 2 and in front of the water also 2.
