An alkene 'A' (molecular formula `C_(5)H_(10)`) on ozonolysis gives a mixture of two compounds 'B' and 'C'. Compound 'B' gives positive Fehling's test and also forms iodoform on treatement with `I_(2)" and "NaOH`. Compound 'C' does not give Fehling's test but forms iodoform. Identify the compounds A, B and C. Write the reaction for ozonolysis and formation of iodoform from B and C.

Explanation

Molecular formula `=C_(5)H_(10)`
Degree of unsaturation `=(C_(n)+1)-(H_(n))/(2)`
where, `C_(n)`=number of carbon atoms
`H_(n)`=number of hydrogen atoms `=(5+1)-(10)/(2)=1` Compound A will be either alkene or cyclic hydrocation. Since, A is undergoing ozonolysis hence A must be an alkene.
