Two compounds (X) and (Y) of the same molecular formula. `C_(4)H_(6)` gave the following reactions:
i) Both discharged colour of `Br_(2)` in `C(Cl_(4))`.
ii) (X) gives a precipate with ammonicial `AgNO_(3)` and on oxidation gives propanoic acid and `CO_(2)`.
iii) (Y) does not give precipitate with ammoniacal `AgNO_(3)` and on oxidation gives oxliac acid and `CO_(2)`.
What is the structural formula of (X) and (Y).

Explanation

(X) is `CH_(3)CH_(2)CH=CH` and (Y) is `H_(2)C=CH-CH=CH_(2)`
