Compound P(C₆H₁₀) does not have any geometrical isomer. ON ozonolysis, two products R(C₃H₄O) and Q(C₃H₆O) are formed. R gives negative iodoform test while Q responds positively towards I₂/NaOH solution. S, another isomer of P is an unsyumetrical alkene and on ozonolysis produces T(C₆H10O₂) which also gives a yellow precipitate with I₂/NaOH solution and also gives positive test with Tollen's reagent. Which of the following does not represent any of the molecules amongst P,Q,R,S & T.
