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.
