Answer
The product will be 1,2-dichloro-2-methylbutane.
The complete reaction is as follows:
Work Step by Step
Here, 2-methyl-1-butene (Alkene) reacts with Chlorine to produce 1,2-dichloro-2-methylbutane as the product. This reaction is an example of Alkene addition reaction where double bond of the alkene breaks down to a single bond when reacts with Chlorine molecule and two Chlorine atoms are added to $C_{1}$ and $C_{2}$ Carbon respectively. Unsaturated hydrocarbons (Alkene and Alkyne) always participate in this type of reaction.
