1,3-dichlorocyclopentane exist in three stereo isomeric forms, of which only two are chiral. If one mole of its achiral stereomer is treated with exactly one mole of its achiral stereomer is treated with exactly with exactly one mole of `NaOH` in aquenous medium and , only mono substitution `(S_(N)2)` and mono-elimination(E2) occur producing chloro-cyclopentanol and chlorocyclopentene, how many different products are expected ?
