Answer:

1. Question⇒ how does iodobenzene react with copper pwder? what is the name of the reaction​?

Explanation:

• Iodobenzene on heating with copper powder in sealed tube froms  diphenyl. This reaction called as ullman reaction.

• C6H5I+CU+C5H6LI↔ C6H5-C6H5+CUI2            ⇔     {Reaction}

    Regards!

Answer 2

When Iodobenzene ( C$_{6}$H$_{5}$I ) is heated with copper powder ( Cu ) , Biphenyl ( C$_{6}$H$_{5}$-C$_{6}$H$_{5}$ ) is formed .

C$_{6}$H$_{5}$I + Cu + C$_{6}$H$_{5}$I →  C$_{6}$H$_{5}$-C$_{6}$H$_{5}$ + CuI$_{2}$      

• The above reaction is known as Ullman reaction .
• This reaction is take place in sealed tube .  
• Biphenyl forms colorless crystals .
• The molar mass of Biphenyl is 154.21 g/mol and the density is 1.04 g/cm³ .
