Question

C2H2 + HCl =C2H4+HCl=C2H2+Br2=C2H4+ Br2=​

Answer 1

C2H4 + Br2 = C2H4Br

C2H2 + HCl = C2H4Cl2

C2H4 + HCl = C2H6Cl2

C2H2 + Br2 = C2H2Br

Answer 2

The reactions you've listed involve the compounds acetylene (C2H2), hydrogen chloride (HCl), ethylene (C2H4), and bromine (Br2). Let's break down each reaction:

1. C2H2 + HCl = C2H4 + HCl: This reaction involves acetylene (C2H2) reacting with hydrogen chloride (HCl) to form ethylene (C2H4) and hydrogen chloride (HCl). The balanced chemical equation for this reaction is:

   C2H2 + HCl -> C2H4 + HCl

2. C2H2 + Br2 = C2H4 + Br2: In this reaction, acetylene (C2H2) reacts with bromine (Br2) to form ethylene (C2H4) and bromine (Br2). The balanced chemical equation for this reaction is:

   C2H2 + Br2 -> C2H4 + Br2

It appears that you have written the same reactions twice in your question. These reactions involve the conversion of acetylene to ethylene in the presence of hydrogen chloride or bromine. The chemical equations provided above represent these reactions.
