Propene, C3H6\text{C}_3\text{H}_6C3H6, reacts with bromine, Br2\text{Br}_2Br2, in an addition reaction.
Which is the balanced symbol equation for this reaction?
C3H6+Br2→C3H5Br+HBr\text{C}_3\text{H}_6 + \text{Br}_2 \rightarrow \text{C}_3\text{H}_5\text{Br} + \text{HBr}C3H6+Br2→C3H5Br+HBr
C3H6+Br2→C3H6Br2\text{C}_3\text{H}_6 + \text{Br}_2 \rightarrow \text{C}_3\text{H}_6\text{Br}_2C3H6+Br2→C3H6Br2
C3H6+2Br2→C3Br6+3H2\text{C}_3\text{H}_6 + 2\text{Br}_2 \rightarrow \text{C}_3\text{Br}_6 + 3\text{H}_2C3H6+2Br2→C3Br6+3H2
C3H6+2Br2→C3H6Br4\text{C}_3\text{H}_6 + 2\text{Br}_2 \rightarrow \text{C}_3\text{H}_6\text{Br}_4C3H6+2Br2→C3H6Br4
