How does acetylene react with
Bromine ? Write the balanced equations for the above reactions. Name the products.

Explanation

(a). Acetylene react with bromine in the presence of `C Cl_(4)` forming an addition compound 1,1,2,2-tetra bromoethane.
`HC-=CH+Br_2 overset(C Cl_(4))to underset("1,2,2,-tetra bromoethane")(H-underset(Br)underset(|)overset(Br)overset(|)(C)-overset(Br)overset(|)(C)-underset(Br)underset(|)overset(Br)overset(|)(C)-H)`
