CH3−CH=CH−CH3→ΔKMnO4/H+X;CH3−CH=CH−CH3→Zn+H2OO3Y;Correct statement among the following is

‘X’ is two moles of CH3COOH.‘Y’ is two moles of CH3CHO.CH3CHO→CH3COOH is oxidation.CH3COOH and HCOOCH3 are functional isomers.CH3CHO and epoxide(ethylene oxide) are functional isomers.CH3CHO is less acidic than CH3COOH.
