Question 26

Butene, C4H8\text{C}_4\text{H}_8C4​H8​, reacts with chlorine, Cl2\text{Cl}_2Cl2​, in an addition reaction.

Which is the balanced symbol equation for this reaction?

A

C4H8+Cl2→C4H7Cl+HCl\text{C}_4\text{H}_8 + \text{Cl}_2 \rightarrow \text{C}_4\text{H}_7\text{Cl} + \text{HCl}C4​H8​+Cl2​→C4​H7​Cl+HCl

B

C4H8+2Cl2→C4H8Cl4\text{C}_4\text{H}_8 + 2\text{Cl}_2 \rightarrow \text{C}_4\text{H}_8\text{Cl}_4C4​H8​+2Cl2​→C4​H8​Cl4​

C

C4H8+Cl2→C4H8Cl2\text{C}_4\text{H}_8 + \text{Cl}_2 \rightarrow \text{C}_4\text{H}_8\text{Cl}_2C4​H8​+Cl2​→C4​H8​Cl2​

D

C4H8+2Cl2→C4Cl8+4H2\text{C}_4\text{H}_8 + 2\text{Cl}_2 \rightarrow \text{C}_4\text{Cl}_8 + 4\text{H}_2C4​H8​+2Cl2​→C4​Cl8​+4H2​
