C2h2+br2= c2h2+2br2=c2h2br4 почему бром 4? объясните пожалуйста c2h2+br2= c2h2+2br2=c2h2br4 почему бром 4? объясните пожалуйста

Answer 1

2 пи связи разрываются, образуется тетрабромацетилен (C2H2Br4)  
C2H2 + 2Br2 → C2H2Br4 ты не уровняла  2 связи ,значит на *2 

Answer 2

Chemical Reaction: C2H2 + Br2 = C2H2Br4

The chemical reaction you mentioned is the reaction between acetylene (C2H2) and bromine (Br2). The balanced equation for this reaction is:

C2H2 + 2Br2 = C2H2Br4

In this reaction, one molecule of acetylene reacts with two molecules of bromine to form one molecule of tetrabromoethane.

Explanation: Why Bromine 4?

The reason why the product is tetrabromoethane (C2H2Br4) is because each bromine atom (Br) in the reactant (Br2) adds to the acetylene (C2H2) molecule, resulting in the formation of four bromine atoms in the product.

When bromine (Br2) reacts with acetylene (C2H2), the double bond in acetylene breaks, and each bromine atom adds to one of the carbon atoms in the acetylene molecule. This results in the formation of a tetrahedral structure where each carbon atom is bonded to two hydrogen atoms and two bromine atoms.

Therefore, the product of the reaction, tetrabromoethane (C2H2Br4), contains four bromine atoms bonded to the two carbon atoms in the acetylene molecule.

I hope this explanation helps! Let me know if you have any further questions.
