Molecules having same molecular formula. But differing in structure (or) spatial orientation of atom is known isomers and phenomenon known as isomerism. Molecules which differ in structural formula are known as structural isomers and phenomenon is known as structural isomerism structural isomerism can be broadly classified as (i) Chain isomerism (ii) Positional isomerism (iii) Functional isomerism (iv) Metamerism (v) Tautomerism Molecules having same molecular formula but differing in spatial orientation are known as stereo isomers and the phenomenon known as stereo isomerism. Stero isomerism can be classified as (i) Geometrical isomerism (ii) Optical isomerism The phenomenon in which molecules having same molecular formula and same functional group but differing in the nature of alkyl group attached to functional group known as

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)
