A hydrocarbon P has molecular formula `C_8H_(16)`, and it does not undergo hydrogenation with raney Ni. A on free radical chlorination yields three monochloro derivatives Q, R and S (all structural isomers) with their molecular formula `C_8 H_(15)Cl`. Only Q can show optical isomerism R. On further chlorination produces a dichloride `C_8 H_(14) Cl_2`, as one of the several isomers which on heating with sodium metal in etheral solution gives bicyclo [2, 2, 2] octane.
If S is dichlorinated, how many isomers would be produced? (exclude stereoisomers)

B. 3
