Question

Give the formula and names of A, B, C and D in the following equation: 

\[\ce{C2H2 ->[H2] A ->[H2] B ->[Br2][-HBr] C ->[Br2][-HBr] D}\]

Answer 1

\[\ce{C2H2 ->[H2] \underset{(A)}{\underset{Ethene}{C2H4}} ->[H2] \underset{(B)}{\underset{Ethane}{C2H6}} ->[Br2][-HBr] \underset{(C)}{\underset{Bromoethane}{C2H5Br}} ->[Br2][-HBr] \underset{(D)}{\underset{Dibromoethane}{C2H4Br}}}\]
