An alkene 'A' (Mol. formula C⁵H¹⁰ on ozonolysis gives a mixture of two compounds 'B' and 'C'. Compound 'B' gives positive Fehling's test and forms an iodoform on treatment with I₂ and NaOH. Compound 'C' does not give Fehling's test but forms an iodoform. Identify the compounds A, B and C. Write the reaction for ozonolysis and formation of iodoform from B and C.

At 25°C the standard emf of cell having reactions involving two electrons change is found to be 0.295 V. The equilibrium constant of the reaction is :
