Passage
A hydrocarbon P has molecular formula C8H16 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 C8H15CI. Only Q can show optical isomerism. R on further chlorination produces a dichloride C8H14CI2 as one of the several isomers which on heating with sodium metal in etheral solution gives bicyclo [2, 2, 2] octane.
Q. Which of the following satisfy the criteria for P ?
