Subjective Type

Give the formula and name of $$A, B, C$$ and $$D$$ in the following equations: $$C_2H_2 \xrightarrow {H_2}\ A \xrightarrow{H_2}\ B\ \underset{-HBr}{\xrightarrow {Br_2}}\ C\ \underset{-HBr}{\xrightarrow {Br_2}}\ D$$

Solution

$$C_2H_2 \xrightarrow {H_2}\ C_2H_4\xrightarrow{H_2}\ C_2H_6 \ \underset{-HBr}{\xrightarrow {Br_2}}\ C_2H_5Br\ \underset{-HBr}{\xrightarrow {Br_2}}\ C_2H_4Br_2$$

$$A=$$ Ethene
$$B=$$ Ethane
$$C=$$ Bromoethane
$$D=$$ Dibromoethane
