Answer:
As shown in the attachment.
Explanation:
In this case, there are two isomers possible. Isomers are compounds that have the same molecular formular but different structural formular.
Considering the hydrocarbon C8H10, which has 8C expected saturated hydrocarbon. however when there is an excess of 8H, we have C8H18 which is the formular of octane, a member of the alkane family and from monosubstitution reaction which involves reaction with halogens (particularly Chlorine), the reaction will be a repeated substitution reaction where chlorine will be replaced with each of the hydrogen.
